Hex Encoding

Hex Encoding & Decoding.


Base64 is a group of binary-to-text encoding schemes that transforms binary data into a sequence of printable characters, limited to a set of 64 unique characters.

URL Encoding

URL encode is a method of encoding a string in a format that can be used in a URL.

Morse Encoding

The Morse Code is a language that people use to communicate with each other. through telegraph, radio, satellite, or with light. The language is a series of. short and long bursts that are heard or seen. The short bursts of sound or light are called “dit”, and the long bursts are called “dah”.

RC4(Randomized Cipher 4)

RC4 (Randomized Cipher 4) is a stream cipher that is designed to be used in conjunction with a stream cipher. It is a stream cipher because it operates on a stream of data rather than a single block of data.


Rabbit uses a 128-bit key and a 64-bit initialization vector.The core component of the cipher is a bitstream generator which encrypts 128 message bits per iteration.

Triple DES

Triple DES or DESede , a symmetric-key algorithm for the encryption of electronic data, is the successor of DES(Data Encryption Standard) and provides more secure encryption than DES.

AES(Advanced Encryption Standard)

An AES (Advanced Encryption Standard) instruction set is a set of instructions that are specifically designed to perform AES encryption and decryption operations efficiently.)


ROT13 is a simple letter substitution cipher that replaces a letter with the 13th letter after it in the Latin alphabet. ROT13 is a special case of the Caesar cipher which was developed in ancient Rome.

Vigenere Cipher

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.

Caesar Cipher

Caesar cipher is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet.

Baconian Cipher

Bacon's cipher or the Baconian cipher is a method of steganographic message encoding devised by Francis Bacon in 1605.
