Encryption

Input

This webpage supports symmetric encryption (i.e. the same key is used for encryption and decryption) of text messages using the Advanced Encryption Standard (AES) with 256-bit block size. Desktop applications suitable also for encryption of files can be downloaded here.

Assymetric encryption (with two different keys, a public one for encryption and a private for decryption) can be reliably performed using the Gnu Privacy Guard.
