Generating keypair

3 declarations

typetype RSAGenKeyCallback = Int -> Int -> IO ()

RSAGenKeyCallback represents a callback function to get informed the progress of RSA key generation.

callback 0 i is called after generating the i-th potential prime number.
While the number is being tested for primality, callback 1 j is called after the j-th iteration (j = 0, 1, ...).
When the n-th randomly generated prime is rejected as not suitable for the key, callback 2 n is called.
When a random p has been found with p-1 relatively prime to e, it is called as callback 3 0.
The process is then repeated for prime q with callback 3 1.

valuegenerateRSAKey

:: Int
The number of bits of the public modulus (i.e. key size). Key sizes with n < 1024 should be considered insecure.
-> Int
The public exponent. It is an odd number, typically 3, 17 or 65537.
-> Maybe RSAGenKeyCallback
A callback function.
-> IO RSAKeyPair
The generated keypair.

generateRSAKey generates an RSA keypair.

valuegenerateRSAKey'

:: Int
The number of bits of the public modulus (i.e. key size). Key sizes with n < 1024 should be considered insecure.
-> Int
The public exponent. It is an odd number, typically 3, 17 or 65537.
-> IO RSAKeyPair
The generated keypair.
