In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure. An alternative, less common term is encipherment.

To encipher or encode is to convert information into cipher or code. In common parlance, "cipher" is synonymous with "code," as they are both a set of steps that encrypt a message; however, the concepts are distinct in cryptography, especially classical cryptography.

Cipher Tools allows for the quick and easy encryption and decryption of classical cryptography algorithms. The application supports the following encodings :
✓ Atbash
✓ Caesar
✓ ROT13
✓ Vigenere
✓ Affine
✓ Rail Fence
✓ Beaufort
✓ Baconian
