Timelock

timelock - simple timelock-based encryption tool
    timelock encrypt <input filename> <output filename>
        encrypts a file, asks for public variables via STDIN, produces all public variables to distribute to STDOUT.
    timelock decrypt <input filename> <output filename>
        decrypts a file, asks for public variables via STDIN.

Uses the RSA-style timelock puzzle to make a ciphertext decryptable, but only after a configured amount of time has passed. See https://people.csail.mit.edu/rivest/pubs/RSW96.pdf for more details.

Encrypt/Decrypt Inputs:

A: A value which will be hashed to serve as the a value. T: The t parameter, or number of squarings.

Encrypt Outputs/Decrypt Inputs:

Modulus: The n value. CK: The encrypted value of the decryption key K, C_K = K + a^(2^t) (mod n)
