(Ruby) Encrypt / Decrypt Secure Strings

Demonstrates how to use the EncryptSecureENC and DecryptSecureENC methods to encrypt/decrypt secure strings. These methods were added in Chilkat v9.5.0.71 (released January 2018).

require 'chilkat'

#  This example requires the Chilkat Crypt API to have been previously unlocked.
#  See Unlock Chilkat Crypt for sample code.

#  Load the secure string with some text.
secStr1 = Chilkat::CkSecureString.new()
success = secStr1.LoadFile("qa_data/txt/helloWorld.txt","utf-8")
if (success != true)
    print "Failed to load helloWorld.txt" + "\n";
    exit
end

crypt = Chilkat::CkCrypt2.new()

crypt.put_CryptAlgorithm("aes")
crypt.put_CipherMode("cbc")
crypt.put_KeyLength(128)
crypt.SetEncodedKey("000102030405060708090A0B0C0D0E0F","hex")
crypt.SetEncodedIV("000102030405060708090A0B0C0D0E0F","hex")
crypt.put_EncodingMode("base64")

#  Return the base64 encoded encrypted contents of secStr1.
encryptedStr = crypt.encryptSecureENC(secStr1)
print "Encrypted string: " + encryptedStr + "\n";

#  Output:
#  Encrypted string: qiq+IFhcjTkEIkZyf31V/g==

#  Decrypt to secStr2:
secStr2 = Chilkat::CkSecureString.new()
crypt.DecryptSecureENC(encryptedStr,secStr2)

#  Access the contents of secStr2
print "Decrypted string: " + secStr2.access() + "\n";

#  Output:
#  Decrypted string: Hello World!
