## Uses of Class
java.security.SignatureException

Packages that use SignatureException
java.security | Provides the classes and interfaces for the security framework.
java.security.cert | Provides classes and interfaces for parsing and managing certificates, certificate revocation lists (CRLs), and certification paths.
javax.security.cert | Provides classes for public key certificates.

Uses of SignatureException in java.security

Methods in java.security that throw SignatureException
`protected abstract byte[]` | `SignatureSpi.engineSign()` Returns the signature bytes of all the data updated so far.
`protected int` | `SignatureSpi.engineSign(byte[] outbuf, int offset, int len)` Finishes this signature operation and stores the resulting signature bytes in the provided buffer `outbuf`, starting at `offset`.
`protected abstract void` | `SignatureSpi.engineUpdate(byte b)` Updates the data to be signed or verified using the specified byte.
`protected abstract void` | `SignatureSpi.engineUpdate(byte[] b, int off, int len)` Updates the data to be signed or verified, using the specified array of bytes, starting at the specified offset.
`protected abstract boolean` | `SignatureSpi.engineVerify(byte[] sigBytes)` Verifies the passed-in signature.
`protected boolean` | `SignatureSpi.engineVerify(byte[] sigBytes, int offset, int length)` Verifies the passed-in signature in the specified array of bytes, starting at the specified offset.
`byte[]` | `Signature.sign()` Returns the signature bytes of all the data updated.
`int` | `Signature.sign(byte[] outbuf, int offset, int len)` Finishes the signature operation and stores the resulting signature bytes in the provided buffer `outbuf`, starting at `offset`.
`void` | `Signature.update(byte b)` Updates the data to be signed or verified by a byte.
`void` | `Signature.update(byte[] data)` Updates the data to be signed or verified, using the specified array of bytes.
`void` | `Signature.update(byte[] data, int off, int len)` Updates the data to be signed or verified, using the specified array of bytes, starting at the specified offset.
`void` | `Signature.update(ByteBuffer data)` Updates the data to be signed or verified using the specified ByteBuffer.
`boolean` | `Signature.verify(byte[] signature)` Verifies the passed-in signature.
`boolean` | `Signature.verify(byte[] signature, int offset, int length)` Verifies the passed-in signature in the specified array of bytes, starting at the specified offset.
`boolean` | `SignedObject.verify(PublicKey verificationKey, Signature verificationEngine)` Verifies that the signature in this SignedObject is the valid signature for the object stored inside, with the given verification key, using the designated verification engine.

Constructors in java.security that throw SignatureException
`SignedObject(Serializable object, PrivateKey signingKey, Signature signingEngine)` Constructs a SignedObject from any Serializable object.

Uses of SignatureException in java.security.cert

Methods in java.security.cert that throw SignatureException
`abstract void` | `X509CRL.verify(PublicKey key)` Verifies that this CRL was signed using the private key that corresponds to the given public key.
`abstract void` | `Certificate.verify(PublicKey key)` Verifies that this certificate was signed using the private key that corresponds to the specified public key.
`abstract void` | `X509CRL.verify(PublicKey key, String sigProvider)` Verifies that this CRL was signed using the private key that corresponds to the given public key.
`abstract void` | `Certificate.verify(PublicKey key, String sigProvider)` Verifies that this certificate was signed using the private key that corresponds to the specified public key.

Uses of SignatureException in javax.security.cert

Methods in javax.security.cert that throw SignatureException
`abstract void` | `Certificate.verify(PublicKey key)` Verifies that this certificate was signed using the private key that corresponds to the specified public key.
`abstract void` | `Certificate.verify(PublicKey key, String sigProvider)` Verifies that this certificate was signed using the private key that corresponds to the specified public key.
