PBKDF2 - Derive Key from Password

See more Encryption Examples

Demonstrates how to derive a symmetric encryption key from a password using PBKDF2. Chilkat2-Python

import chilkat2

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

crypt = chilkat2.Crypt2()

pw = "password"

pwCharset = "utf-8"

# Such as sha256, sha512
hashAlg = "sha256"

# 16 bytes
saltHex = "78578E5A5D63CB0668AB39B21C8637FA"

iterationCount = 100000

# Derive a 256-bit key from the password.
outputBitLen = 256

# The derived key is returned as a hex or base64 encoded string.
# (Note: The salt argument must be a string that also uses
# the same encoding.)
enc = "hex"

hexKey = crypt.Pbkdf2(pw,pwCharset,hashAlg,saltHex,iterationCount,outputBitLen,enc)

print(hexKey)

# Sample output:
