Substitute

A substitution cipher allowing you to specify bytes to replace with other byte values. This can be used to create Caesar ciphers but is more powerful as any byte value can be substituted, not just letters, and the substitution values need not be in order. Enter the bytes you want to replace in the Plaintext field and the bytes to replace them with in the Ciphertext field. Substitute lives in the Cryptography category of the fx menu.

Parameters

Parameter	Type	Required	Default	Description
