Computing the hash for a file of any size. Ruby

require 'chilkat'

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

crypt = Chilkat::CkCrypt2.new()

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

filename = "something.zip"

crypt.put_HashAlgorithm("sha1")
crypt.put_EncodingMode("hex")

# Other possible EncodingMode settings are: 
# "quoted-printable", "base64", "base32", and "url"

hash = crypt.hashFileENC(filename)
print "SHA1:" + "\n";
print hash + "\n";

# Hash using MD2
crypt.put_HashAlgorithm("md2")
hash = crypt.hashFileENC(filename)
print "MD2:" + "\n";
print hash + "\n";

# Hash using MD5
crypt.put_HashAlgorithm("md5")
hash = crypt.hashFileENC(filename)
print "MD5:" + "\n";
print hash + "\n";

# Hash using SHA-256
crypt.put_HashAlgorithm("sha256")
hash = crypt.hashFileENC(filename)
print "SHA256:" + "\n";
print hash + "\n";

# Hash using SHA-384
crypt.put_HashAlgorithm("sha384")
hash = crypt.hashFileENC(filename)

print hash + "\n";

# Hash using SHA-512
crypt.put_HashAlgorithm("sha512")

# 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
crypt.put_HashAlgorithm("haval")

crypt.put_KeyLength(256)
