Time Lock Encryption Class

Time Lock Encryption Class

Implementation of timed-release crypto., _(*1)

This class can encrypt data using key generated for a time period., _(*2)

It takes an expression that defines a given time period and generates a key by creating iteratively hashes of the initial key in a cycle until the specified time as passed., _(*3)

The class returns the encrypted data using the Fernet class with the generated key., _(*4)

It can also decrypt previously encrypted data by regenerating the encryption key the same number of iterations that it were used to generate the key when the data was encrypted., _(*5)

• PHP 5.3.3 or later
• hash extension
• openssl or mcrypt extension
