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

*  Any type of file may be hashed.
*  There is  no size limitation because the file is consumed
*  in streaming mode internally.

lcFilename = "something.zip"

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

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

lcHash = loCrypt.HashFileENC(lcFilename)
? "SHA1:"
? lcHash

*  Hash using MD2
loCrypt.HashAlgorithm = "md2"
lcHash = loCrypt.HashFileENC(lcFilename)
? "MD2:"
? lcHash

*  Hash using MD5
loCrypt.HashAlgorithm = "md5"

*  Hash using SHA-256
loCrypt.HashAlgorithm = "sha256"

? "SHA256:"
? lcHash

*  Hash using SHA-384
loCrypt.HashAlgorithm = "sha384"

*  Hash using SHA-512
loCrypt.HashAlgorithm = "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
