Encoding

List of commonly used string encoding techniques.

Encoding != Encryption

tip

Use DenCode to guess the encoding of a cipher text.

Percent-encoding​

Often has the form %XX where XX is the hexadecimal representation of a character.

Typically used in URLs to encode special characters that are not allowed.

tip
  • Sometimes space characters are encoded as + instead of %20.
  • If you see %25 many times, the string may be double-encoded.

Base64​

Often ends with = or ==.

Typically used to encode binary data into ASCII characters.
