Workaround for the deprecated Crypt2.DecryptBytesENC method

Shows how to replace the deprecated DecryptBytesENC method. (Chilkat is moving away from the use of CkByteData.) Ruby

require 'chilkat'

success = false

crypt = Chilkat::CkCrypt2.new()

crypt.put_CryptAlgorithm("aes")
crypt.put_CipherMode("cbc")
crypt.put_KeyLength(128)
crypt.put_PaddingScheme(0)
crypt.SetEncodedKey("000102030405060708090A0B0C0D0E0F","hex")
crypt.SetEncodedIV("000102030405060708090A0B0C0D0E0F","hex")

success = false

# ------------------------------------------------------------------------
# The EncryptBytesENC and DecryptBytesENC methods are deprecated:

unencryptedBytes = Chilkat::CkByteData.new()
unencryptedBytes.appendEncoded("AABBCCDDEEFF01020304","hex")

decryptedBytes = Chilkat::CkByteData.new()

crypt.put_EncodingMode("hex")
encryptedAsHex = crypt.encryptBytesENC(unencryptedBytes)
print "Encrypted: " + encryptedAsHex + "\n";

success = crypt.DecryptBytesENC(encryptedAsHex,decryptedBytes)

# ------------------------------------------------------------------------
# Replace the above CkByteData usage with the following code:
# (Chilkat is moving away from using CkByteData)

bd = Chilkat::CkBinData.new()
bd.AppendEncoded("AABBCCDDEEFF01020304","hex")

# in-place encrypt, then get as hex.
crypt.EncryptBd(bd)
encryptedAsHex = bd.getEncoded("hex")
print "Encrypted: " + encryptedAsHex + "\n";

# load from hex, then decrypt.
bd2 = Chilkat::CkBinData.new()
bd2.AppendEncoded(encryptedAsHex,"hex")
crypt.DecryptBd(bd2)
print "Decrypted: " + bd2.getEncoded("hex") + "\n";
