Hex Encode & Decode

Delimiter
Delimiter
Bytes Per Line

Encode: Converts the input string to hexadecimal bytes separated by the specified delimiter.

e.g. The UTF-8 encoded string "A.Tools" becomes "41 2e 54 6f 6f 6c 73"


Decode: Converts a hexadecimal byte string back into its raw value.

e.g. "41 2e 54 6f 6f 6c 73" becomes the UTF-8 encoded string "A.Tools"

The Vigenère Cipher is a method of encrypting alphabetic text where each letter of the plaintext is encoded with a different Caesar Cipher, whose increment is determined by the corresponding letter of another text, the key.

Atbash Cipher is a substitution cipher with a specific key where the letters of the alphabet are reversed. I.e. all 'A's are replaced with 'Z's, all 'B's are replaced with 'Y's, and so on. It was originally used for the Hebrew alphabet, but can be used for any alphabet.
