Generate Secret Key from Password

The GenEncodedSecretKey method provides a way to produce a secret key from an arbitrarily sized password string. The secret key produced will be equal in bit length to the KeyLength. A given string passed to GenEncodedSecretKey will always produce the same key. (In other words, this is really a hash function and not a random key generator.)

crypt = chilkat.CkCrypt2()

success = crypt.UnlockComponent("Anything for 30-day Trial")
if (success != True):
    print "Crypt component unlock failed"
    sys.exit()

crypt.put_CryptAlgorithm("aes")
crypt.put_KeyLength(128)

#  Transform an arbitrary-length password to a secret key
#  equal in bit-length to the KeyLength:

hexKey = crypt.genEncodedSecretKey("my_password","hex")

#  Set the secret key:
crypt.SetEncodedKey(hexKey,"hex")

#  The hexKey is 16 bytes in length:
print hexKey
