Groovy SHA1 generator

gistfile1.groovy

import java.security.*

String  password = "toto\n"
MessageDigest sha1 = MessageDigest.getInstance("SHA1")
byte[] digest  = sha1.digest(password.getBytes())
System.out.println(new  BigInteger(1, digest).toString(16))

for groovy 2.5 things are much easier:

def value = 'IamASecret'
 
def md5 = value.md5()
 
// We can provide hash algorithm with digest method.
def md2 = value.digest('MD2')
def sha1 = value.digest('SHA-1')
def sha256 = value.digest('SHA-256')
def sha384 = value.digest('SHA-384')
def sha512 = value.digest('SHA-512')
assert md5 == 'a5f3147c32785421718513f38a20ca44'
assert md2 == '832cbe3966e186194b1203c00ef47488'
assert sha1 == '52ebfed118e0a411e9d9cbd60636fc9dea718928'
assert sha256 == '4f5e3d486d1fd6c822a81aa0b93d884a2a44daf2eb69ac779a91bc76de512cbe'
assert sha384 == '2a46d29c961ae809d4b7da941ca46e23f4ccbcc08186a8a6b2e79b2f3074d06221a3ab1dcd4ca3e9ffa2281da1f200fe'
assert sha512 == '9a0388c0f8dab97d1a0908706b894cd90fa0076154535922cb79943c7a8430cbd9bb7ea21cf284d6c9dc95f5b519dbec1f195f58818039f9f5cbfcacdabee13d'
