Symmetric-key Encryption Tools

Category: Cipher Suite

The Cipher tools for symmetric encryption easily can encrypt text messages online. The same key is used for both encryption and decryption, which makes the difference to a asymmetric encryption. If you want to send someone an encrypted message, one must therefore know the secret key before decrypting it. The free tools for symmetric encryption can be used e.g. to exchange secret messages with each other, that no one else will be able to read.
