Hash Algorithms: SHA-1, HAVAL, MD2, MD5, SHA-256, SHA-384, SHA-512

How to create hashes (message digests) for strings.

LOCAL loCrypt
LOCAL lnSuccess
LOCAL s
LOCAL lcHash

loCrypt = CreateObject('Chilkat.Crypt2')

*  Any string argument automatically begins the 30-day trial.

lnSuccess = loCrypt.UnlockComponent("30-day trial")
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX("Crypt component unlock failed")
    QUIT
ENDIF

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

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

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

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
