ARC4 PRNG (Pseudo Random Number Generator)

See more Encryption Examples

Uses the ARC4 stream encryption algorithm as a pseudo random number generator. Chilkat2-Python

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

crypt = chilkat2.Crypt2()

# Set the encryption algorithm to ARC4:	
crypt.CryptAlgorithm = "arc4"

# We want the encrypted output to be a hex-encoded string.
crypt.EncodingMode = "hex"

key = "000102030405060708090A0B0C0D0E0F"
data = "12345678"

# Key length is 128 bits in this example.
crypt.KeyLength = 128
crypt.SetEncodedKey(key,"hex")

# Generate 16 "random" 8-byte blocks, encoded as hex strings.
# This example will generate the identical output each time
# it is run.
