CFMX_COMPAT

Ruby implementation of the CFMX_COMPAT algorithm within ColdFusion. This will allow you to encrypt and decrypt strings using the CFMX_COMPAT algorithm.

The ColdFusion encrypt() and decrypt() functions also encode the result after encryption and automatically decode before decryption. This gem applies the same encoding and decoding behaviours as ColdFusion.

Base64: the Base64 algorithm, as specified by IETF RFC 2045.
Hex: the characters A-F0-9 represent the hexadecimal byte values.
UU: the UUEncode algorithm (DEFAULT).

The Ruby implementation here is translated from one found in Railo and a C# implementation of that.

Installation

Add this line to your application's Gemfile:

gem 'cfmx_compat'

And then execute:

$ bundle

Or install it yourself as:

$ gem install cfmx_compat

Usage

In Ruby, using this gem:

key = "secretkey"
plain = "plain text value"

encrypted = CfmxCompat.encrypt(plain, key)
decrypted = CfmxCompat.decrypt(encrypted, key)
plain == decrypted # true

encrypted = CfmxCompat.encrypt(plain, key, "uu")
decrypted = CfmxCompat.decrypt(encrypted, key, "uu")
plain == decrypted # true

encrypted = CfmxCompat.encrypt(plain, key, "hex")
decrypted = CfmxCompat.decrypt(encrypted, key, "hex")
plain == decrypted # true

encrypted = CfmxCompat.encrypt(plain, key, "base64")
decrypted = CfmxCompat.decrypt(encrypted, key, "base64")
plain == decrypted # true

Is the same as this in ColdFusion:

<cfscript>
key = "secretkey";
plain = "plain text value";

encrypted = encrypt(plain, key);
decrypted = decrypt(encrypted, key);
decrypted == plain; # true

encrypted = encrypt(plain, key, "CFMX_COMPAT", "uu");
decrypted = decrypt(encrypted, key, "CFMX_COMPAT", "uu");
decrypted == plain; # true

encrypted = encrypt(plain, key, "CFMX_COMPAT", "hex");
decrypted = decrypt(encrypted, key, "CFMX_COMPAT", "hex");
decrypted == plain; # true

encrypted = encrypt(plain, key, "CFMX_COMPAT", "base64");
decrypted = decrypt(encrypted, key, "CFMX_COMPAT", "base64");
decrypted == plain; # true
</cfscript>
