Description of Sourceguardian - Obfuscation And Encryption :
Sourceguardian - Obfuscation And Encryption is a multi-platform compatible script that allows you to protect your source code in four very powerful ways: Encrypt it, Obfuscate it, Time Limit (for trialware) and IP limit (so it only runs on one IP address). It's a great alternative to Zend Encoder, but offers some important advantages - notably protected scripts do not require any changes to default server / PHP installation and will run on virtually any hosting account.
