Secret Key Packet Formats

The Secret Key and Secret Subkey packets contain all the data of the Public Key and Public Subkey packets, with additional algorithm- specific secret key data appended, in encrypted form.

The packet contains:

- A Public Key or Public Subkey packet, as described above
- One octet indicating string-to-key usage conventions. 0 indicates that the secret key data is not encrypted. 255 indicates that a string-to-key specifier is being given. Any other value is a symmetric-key encryption algorithm specifier.
- [Optional] If string-to-key usage octet was 255, a one-octet symmetric encryption algorithm.
- [Optional] If string-to-key usage octet was 255, a string-to-key specifier. The length of the string-to-key specifier is implied by its type, as described above.
- [Optional] If secret data is encrypted, eight-octet Initial Vector (IV).
- Encrypted multi-precision integers comprising the secret key data. These algorithm-specific fields are as described below.
- Two-octet checksum of the plaintext of the algorithm-specific portion (sum of all octets, mod 65536).

Algorithm Specific Fields for RSA secret keys:

- multiprecision integer (MPI) of RSA secret exponent d.
- MPI of RSA secret prime value p.
- MPI of RSA secret prime value q (p < q).
- MPI of u, the multiplicative inverse of p, mod q.

Algorithm Specific Fields for DSA secret keys:

- MPI of DSA secret exponent x.

Algorithm Specific Fields for Elgamal secret keys:

- MPI of Elgamal secret exponent x.

Secret MPI values can be encrypted using a passphrase. If a string- to-key specifier is given, that describes the algorithm for converting the passphrase to a key, else a simple MD5 hash of the passphrase is used. Implementations SHOULD use a string-to-key specifier; the simple hash is for backward compatibility. The cipher for encrypting the MPIs is specified in the secret key packet.

Encryption/decryption of the secret data is done in CFB mode using the key created from the passphrase and the Initial Vector from the packet. A different mode is used with V3 keys (which are only RSA) than with other key formats. With V3 keys, the MPI bit count prefix (i.e., the first two octets) is not encrypted. Only the MPI non- prefix data is encrypted. Furthermore, the CFB state is resynchronized at the beginning of each new MPI value, so that the CFB block boundary is aligned with the start of the MPI data.

With V4 keys, a simpler method is used. All secret MPI values are encrypted in CFB mode, including the MPI bitcount prefix.

The 16-bit checksum that follows the algorithm-specific portion is the algebraic sum, mod 65536, of the plaintext of all the algorithm- specific octets (including MPI prefix and data). With V3 keys, the checksum is stored in the clear. With V4 keys, the checksum is encrypted like the algorithm-specific data. This value is used to check that the passphrase was correct.

Key Packet Variants

5.5.1.1. Public Key Packet (Tag 6)

A Public Key packet starts a series of packets that forms an OpenPGP key (sometimes called an OpenPGP certificate).

5.5.1.2. Public Subkey Packet (Tag 14)

A Public Subkey packet (tag 14) has exactly the same format as a Public Key packet, but denotes a subkey. One or more subkeys may be associated with a top-level key. By convention, the top-level key provides signature services, and the subkeys provide encryption services.

Note: in PGP 2.6.x, tag 14 was intended to indicate a comment packet. This tag was selected for reuse because no previous version of PGP ever emitted comment packets but they did properly ignore them. Public Subkey packets are ignored by PGP 2.6.x and do not cause it to fail, providing a limited degree of backward compatibility.

5.5.1.3. Secret Key Packet (Tag 5)

A Secret Key packet contains all the information that is found in a Public Key packet, including the public key material, but also includes the secret key material after all the public key fields.

5.5.1.4. Secret Subkey Packet (Tag 7)

A Secret Subkey packet (tag 7) is the subkey analog of the Secret Key packet, and has exactly the same format.

5.5.2. Public Key Packet Formats

There are two versions of key-material packets. Version 3 packets were first generated by PGP 2.6. Version 2 packets are identical in format to Version 3 packets, but are generated by PGP 2.5 or before. V2 packets are deprecated and they MUST NOT be generated. PGP 5.0 introduced version 4 packets, with new fields and semantics. PGP 2.6.x will not accept key-material packets with versions greater than 3.

OpenPGP implementations SHOULD create keys with version 4 format. An implementation MAY generate a V3 key to ensure interoperability with old software; note, however, that V4 keys correct some security deficiencies in V3 keys. These deficiencies are described below. An implementation MUST NOT create a V3 key with a public key algorithm other than RSA.

A version 3 public key or public subkey packet contains:

- A one-octet version number (3).
- A four-octet number denoting the time that the key was created.
- A two-octet number denoting the time in days that this key is valid. If this number is zero, then it does not expire.
- A one-octet number denoting the public key algorithm of this key
- A series of multi-precision integers comprising the key material:
  - a multiprecision integer (MPI) of RSA public modulus n;
  - an MPI of RSA public encryption exponent e.

V3 keys SHOULD only be used for backward compatibility because of three weaknesses in them. First, it is relatively easy to construct a V3 key that has the same key ID as any other key because the key ID is simply the low 64 bits of the public modulus. Secondly, because the fingerprint of a V3 key hashes the key material, but not its length, which increases the opportunity for fingerprint collisions. Third, there are minor weaknesses in the MD5 hash algorithm that make developers prefer other algorithms. See below for a fuller discussion of key IDs and fingerprints.

typedef struct pgpPktKeyV4_s * pgpPktKeyV4

The version 4 format is similar to the version 3 format except for the absence of a validity period.

This has been moved to the signature packet. In addition, fingerprints of version 4 keys are calculated differently from version 3 keys, as described in section "Enhanced Key Formats."

A version 4 packet contains:

- A one-octet version number (4).
- A four-octet number denoting the time that the key was created.
- A one-octet number denoting the public key algorithm of this key
- A series of multi-precision integers comprising the key material. This algorithm-specific portion is:

Algorithm Specific Fields for RSA public keys:

- multiprecision integer (MPI) of RSA public modulus n;
- MPI of RSA public encryption exponent e.

Algorithm Specific Fields for DSA public keys:

- MPI of DSA prime p;
- MPI of DSA group order q (q is a prime divisor of p-1);
- MPI of DSA group generator g;
- MPI of DSA public key value y (= g**x where x is secret).

Algorithm Specific Fields for Elgamal public keys:

- MPI of Elgamal prime p;
- MPI of Elgamal group generator g;
- MPI of Elgamal public key value y (= g**x where x is secret).

typedef struct pgpPktLdata_s pgpPktLdata

typedef struct pgpPktOnepass_s * pgpPktOnepass

5.4.

One-Pass Signature Packets (Tag 4)

The One-Pass Signature packet precedes the signed data and contains enough information to allow the receiver to begin calculating any hashes needed to verify the signature. It allows the Signature Packet to be placed at the end of the message, so that the signer can compute the entire signed message in one pass.

A One-Pass Signature does not interoperate with PGP 2.6.x or earlier.

The body of this packet consists of:

- A one-octet version number. The current version is 3.
- A one-octet signature type. Signature types are described in section 5.2.1.
- A one-octet number describing the hash algorithm used.
- A one-octet number describing the public key algorithm used.
- An eight-octet number holding the key ID of the signing key.
- A one-octet number holding a flag showing whether the signature is nested. A zero value indicates that the next packet is another One-Pass Signature packet that describes another signature to be applied to the same message data.

Note that if a message contains more than one one-pass signature, then the signature packets bracket the message; that is, the first signature packet after the message corresponds to the last one-pass packet and the final signature packet corresponds to the first one- pass packet.

typedef struct pgpPktPubkey_s pgpPktPubkey

5.1.

Public-Key Encrypted Session Key Packets (Tag 1)

A Public-Key Encrypted Session Key packet holds the session key used to encrypt a message. Zero or more Encrypted Session Key packets (either Public-Key or Symmetric-Key) may precede a Symmetrically Encrypted Data Packet, which holds an encrypted message. The message is encrypted with the session key, and the session key is itself encrypted and stored in the Encrypted Session Key packet(s). The Symmetrically Encrypted Data Packet is preceded by one Public-Key Encrypted Session Key packet for each OpenPGP key to which the message is encrypted. The recipient of the message finds a session key that is encrypted to their public key, decrypts the session key, and then uses the session key to decrypt the message.

The body of this packet consists of:

- A one-octet number giving the version number of the packet type. The currently defined value for packet version is 3. An implementation should accept, but not generate a version of 2, which is equivalent to V3 in all other respects.
- An eight-octet number that gives the key ID of the public key that the session key is encrypted to.
- A one-octet number giving the public key algorithm used.
- A string of octets that is the encrypted session key. This string takes up the remainder of the packet, and its contents are dependent on the public key algorithm used.

Algorithm Specific Fields for RSA encryption

- multiprecision integer (MPI) of RSA encrypted value m**e mod n.

Algorithm Specific Fields for Elgamal encryption:

- MPI of Elgamal (Diffie-Hellman) value g**k mod p.
- MPI of Elgamal (Diffie-Hellman) value m * y**k mod p.

typedef union pgpPktSig_u * pgpPktSig

5.2.

Signature Packet (Tag 2)

A signature packet describes a binding between some public key and some data. The most common signatures are a signature of a file or a block of text, and a signature that is a certification of a user ID.

Two versions of signature packets are defined. Version 3 provides basic signature information, while version 4 provides an expandable format with subpackets that can specify more information about the signature. PGP 2.6.x only accepts version 3 signatures.

Implementations MUST accept V3 signatures. Implementations SHOULD generate V4 signatures. Implementations MAY generate a V3 signature that can be verified by PGP 2.6.x.

Note that if an implementation is creating an encrypted and signed message that is encrypted to a V3 key, it is reasonable to create a V3 signature.

typedef struct pgpPktSigV3_s * pgpPktSigV3

5.2.2.

Version 3 Signature Packet Format

The body of a version 3 Signature Packet contains:

- One-octet version number (3).
- One-octet length of following hashed material. MUST be 5.
  - One-octet signature type.
  - Four-octet creation time.
- Eight-octet key ID of signer.
- One-octet public key algorithm.
- One-octet hash algorithm.
- Two-octet field holding left 16 bits of signed hash value.
- One or more multi-precision integers comprising the signature.

Algorithm Specific Fields for RSA signatures:

- multiprecision integer (MPI) of RSA signature value m**d.

Algorithm Specific Fields for DSA signatures:

- MPI of DSA value r.
- MPI of DSA value s.

typedef struct pgpPktSigV4_s * pgpPktSigV4

5.2.3.

Version 4 Signature Packet Format

The body of a version 4 Signature Packet contains:

- One-octet version number (4).
- One-octet signature type.
- One-octet public key algorithm.
- One-octet hash algorithm.
- Two-octet scalar octet count for following hashed subpacket data. Note that this is the length in octets of all of the hashed subpackets; a pointer incremented by this number will skip over the hashed subpackets.
- Hashed subpacket data. (zero or more subpackets)
- Two-octet scalar octet count for following unhashed subpacket data. Note that this is the length in octets of all of the unhashed subpackets; a pointer incremented by this number will skip over the unhashed subpackets.
- Unhashed subpacket data. (zero or more subpackets)
- Two-octet field holding left 16 bits of signed hash value.
- One or more multi-precision integers comprising the signature.

typedef struct pgpPktSymkey_s pgpPktSymkey

5.3.

Symmetric-Key Encrypted Session-Key Packets (Tag 3)

The Symmetric-Key Encrypted Session Key packet holds the symmetric- key encryption of a session key used to encrypt a message. Zero or more Encrypted Session Key packets and/or Symmetric-Key Encrypted Session Key packets may precede a Symmetrically Encrypted Data Packet that holds an encrypted message. The message is encrypted with a session key, and the session key is itself encrypted and stored in the Encrypted Session Key packet or the Symmetric-Key Encrypted Session Key packet.

If the Symmetrically Encrypted Data Packet is preceded by one or more Symmetric-Key Encrypted Session Key packets, each specifies a passphrase that may be used to decrypt the message. This allows a message to be encrypted to a number of public keys, and also to one or more pass phrases. This packet type is new, and is not generated by PGP 2.x or PGP 5.0.

The body of this packet consists of:

- A one-octet version number. The only currently defined version is 4.
- A one-octet number describing the symmetric algorithm used.
- A string-to-key (S2K) specifier, length as defined above.
- Optionally, the encrypted session key itself, which is decrypted with the string-to-key object.

typedef enum pgpSigType_e pgpSigType

| 5.2.1. Signature Types There are a number of possible meanings for a signature, which are specified in a signature type octet in any given signature.

typedef enum pgpSubType_e pgpSubType

5.2.3.1.

Signature Subpacket Specification

The subpacket fields consist of zero or more signature subpackets. Each set of subpackets is preceded by a two-octet scalar count of the length of the set of subpackets.

Each subpacket consists of a subpacket header and a body. The header consists of:

- the subpacket length (1, 2, or 5 octets)
- the subpacket type (1 octet) and is followed by the subpacket specific data.

The length includes the type octet but not this length. Its format is similar to the "new" format packet header lengths, but cannot have partial body lengths. That is:

           if the 1st octet <  192, then
               lengthOfLength = 1
               subpacketLen = 1st_octet

           if the 1st octet >= 192 and < 255, then
               lengthOfLength = 2
               subpacketLen = ((1st_octet - 192) << 8) + (2nd_octet) + 192

           if the 1st octet = 255, then
               lengthOfLength = 5
               subpacket length = [four-octet scalar starting at 2nd_octet]

The value of the subpacket type octet may be:

           2 = signature creation time
           3 = signature expiration time
           4 = exportable certification
           5 = trust signature
           6 = regular expression
           7 = revocable
           9 = key expiration time
           10 = placeholder for backward compatibility
           11 = preferred symmetric algorithms
           12 = revocation key
           16 = issuer key ID
           20 = notation data
           21 = preferred hash algorithms
           22 = preferred compression algorithms
           23 = key server preferences
           24 = preferred key server
           25 = primary user id
           26 = policy URL
           27 = key flags
           28 = signer's user id
           29 = reason for revocation
           100 to 110 = internal or user-defined

An implementation SHOULD ignore any subpacket of a type that it does not recognize.

Bit 7 of the subpacket type is the "critical" bit. If set, it denotes that the subpacket is one that is critical for the evaluator of the signature to recognize. If a subpacket is encountered that is marked critical but is unknown to the evaluating software, the evaluator SHOULD consider the signature to be in error.
