Crypto.PubKey.RSA

Description

 
Synopsis

Documentation

data Error Source #

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.

data PrivateKey Source #

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.

Generation function

generateWith Source #

Arguments

:: (Integer, Integer)

chosen distinct primes p and q

-> Int

size in bytes

-> Integer

RSA public exponent e

-> Maybe (PublicKey, PrivateKey) 

Generate a key pair given p and q.

p and q need to be distinct prime numbers.

e need to be coprime to phi=(p-1)*(q-1). If that's not the case, the function will not return a key pair. A small hamming weight results in better performance.

  • e=0x10001 is a popular choice
  • e=3 is popular as well, but proven to not be as secure for some cases.

generate Source #

Arguments

:: MonadRandom m 
=> Int

size in bytes

-> Integer

RSA public exponent e

-> m (PublicKey, PrivateKey) 

generate a pair of (private, public) key of size in bytes.

generateBlinder Source #

Arguments

:: MonadRandom m 
=> Integer

RSA public N parameter.

-> m Blinder 

Generate a blinder to use with decryption and signing operation

the unique parameter apart from the random number generator is the public key value N.
