Trouble using scrypt #51

Closed deeuu closed 3 years ago

deeuu commented 3 years ago

Hi,

I'm trying to import and use scrypt, but am having issues when trying to run an example based on the test suite:

import nimcrypto / [scrypt]

func myscrypt[T, M](password: openArray[T], salt: openArray[M],
                   N, r, p, keyLen: static[int]): array[keyLen, byte] =
  let (xyvLen, bLen) = scryptCalc(N, r, p)
  var xyv = newSeq[uint32](xyvLen)
  var b = newSeq[byte](bLen)
  discard scrypt(password, salt, N, r, p, xyv, b, result)

discard myscrypt(password = "", salt = "", N = 16, r = 1, p = 1, keyLen = 64)
nim c -r main.nim

It looks like I have to import hmac to get around it, i.e.

import nimcrypto / [scrypt, hmac]

Any help is much appreciated!
