# Documentation

data Error

error possible during encryption, decryption or signing.

Constructors

MessageSizeIncorrect | the message to decrypt is not of the correct size (need to be == private_size)
MessageTooLong | the message to encrypt is too long
MessageNotRecognized | the message decrypted doesn't have a PKCS15 structure (0 2 .. 0 msg)
SignatureTooLong | the message's digest is too long
InvalidParameters | some parameters lead to breaking assumptions.

Instances

Eq Error |
Show Error |

data Blinder

Blinder which is used to obfuscate the timing of the decryption primitive (used by decryption and signing).

Constructors

Blinder !Integer !Integer |

Instances

Eq Blinder |
Show Blinder |

data PublicKey

Represent a RSA public key

Constructors

PublicKey |
Fields public_size :: Int size of key in bytes public_n :: Integer public p*q public_e :: Integer public exponant e

Instances

Eq PublicKey |
Data PublicKey |
Read PublicKey |
Show PublicKey |
NFData PublicKey |

data PrivateKey

Represent a RSA private key.

Only the pub, d fields are mandatory to fill.

p, q, dP, dQ, qinv are by-product during RSA generation, but are useful to record here to speed up massively the decrypt and sign operation.

implementations can leave optional fields to 0.

Constructors

PrivateKey |
Fields private_pub :: PublicKey public part of a private key (size, n and e) private_d :: Integer private exponant d private_p :: Integer p prime number private_q :: Integer q prime number private_dP :: Integer d mod (p-1) private_dQ :: Integer d mod (q-1) private_qinv :: Integer q^(-1) mod p

Instances

Eq PrivateKey |
Data PrivateKey |
Read PrivateKey |
Show PrivateKey |
NFData PrivateKey |

newtype KeyPair

Represent RSA KeyPair

note the RSA private key contains already an instance of public key for efficiency

Constructors

KeyPair PrivateKey |

Instances

Eq KeyPair |
Data KeyPair |
Read KeyPair |
Show KeyPair |
NFData KeyPair |

toPublicKey :: KeyPair -> PublicKey
