Synopsis

- encrypt :: ([Octet], [Octet]) -> [Octet] -> [Octet]
- decrypt :: ([Octet], [Octet]) -> [Octet] -> [Octet]

# Function Types

encrypt :: ([Octet], [Octet]) -> [Octet] -> [Octet]

Take the modulus of the RSA key and the public exponent expressed as lists of octets and the plaintext also expressed as a list of octets and return the ciphertext as a list of octets. Of course, these are all large integers but using lists of octets makes everything easier. See http://www.rsasecurity.com/rsalabs/pkcs/pkcs-1/index.html for more details.

decrypt :: ([Octet], [Octet]) -> [Octet] -> [Octet]

Take the modulus of the RSA key and the private exponent expressed as lists of octets and the ciphertext also expressed as a list of octets and return the plaintext as a list of octets.
