Hash the Contents of a String (SHA256 and other hash algorithms)

See more Encryption Examples

Demonstrates how to hash the contents of a string using SHA256, SHA384, SHA512, MD2, MD5, HAVAL, RIPEMD, etc. Visual FoxPro

LOCAL loCrypt
LOCAL loHashBytes
LOCAL loSb

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

loCrypt = CreateObject('Chilkat.Crypt2')

* Choose the hash algorithm.
* Can be  "sha1", "sha256", "sha384", "sha512", "md2", "md5", "haval", "ripemd128", "ripemd160","ripemd256", or "ripemd320".
loCrypt.HashAlgorithm = "sha256"

* The byte representation of the string matters when hashing. 
* Tell Chilkat that we want to use the utf-8 byte representation.
loCrypt.Charset = "utf-8"

loHashBytes = loCrypt.HashString("They who can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety.")

* Let's examine the hash as a hex string.
loSb = CreateObject('Chilkat.StringBuilder')
loSb.AppendEncoded(loHashBytes,"hex")
? "SHA256 hash = " + loSb.GetAsString()
