(Visual FoxPro) Hash Algorithms: SHA-1, HAVAL, MD2, MD5, SHA-256, SHA-384, SHA-512

How to create hashes (message digests) for strings.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows

LOCAL loCrypt
LOCAL s
LOCAL lcHash

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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Crypt2')
loCrypt = CreateObject('Chilkat.Crypt2')

s = "The quick brown fox jumps over the lazy dog"

loCrypt.HashAlgorithm = "sha1"
loCrypt.EncodingMode = "hex"

* Other possible EncodingMode settings are: 
* "quoted-printable", "base64","url", and many more..

lcHash = loCrypt.HashStringENC(s)
? "SHA1: " + lcHash

* Hash using MD2
loCrypt.HashAlgorithm = "md2"
lcHash = loCrypt.HashStringENC(s)
? "MD2: " + lcHash

* Hash using MD5
loCrypt.HashAlgorithm = "md5"
lcHash = loCrypt.HashStringENC(s)
? "MD5: " + lcHash

* Note: SHA-2 is a set of cryptographic hash functions (SHA-224, SHA-256, SHA-384, SHA-512)

* Hash using SHA-256
loCrypt.HashAlgorithm = "sha256"
lcHash = loCrypt.HashStringENC(s)
? "SHA256: " + lcHash

* Hash using SHA-384
loCrypt.HashAlgorithm = "sha384"
lcHash = loCrypt.HashStringENC(s)
? "SHA384: " + lcHash

* Hash using SHA-512
loCrypt.HashAlgorithm = "sha512"
lcHash = loCrypt.HashStringENC(s)
? "SHA512: " + lcHash

* Hash using HAVAL
* There are two additional properties relevant to HAVAL:
* HavalRounds, and KeyLength.
* HavalRounds can have values of 3, 4, or 5.
* KeyLength can have values of 128, 160, 192, 224, or 256
loCrypt.HashAlgorithm = "haval"
loCrypt.HavalRounds = 5
loCrypt.KeyLength = 256
lcHash = loCrypt.HashStringENC(s)
? "Haval: " + lcHash
