PPEncode

Charset

PPEncode is a Perl subset that limits source code to only Perl keywords. Yoshino TAKESAKO defined the keywords in 2005.

PPEncode can be used to write Perl code using only Perl reserved words. It's a Perl program to generate a PPEncode program that outputs a given string or an encoding method to represent a text with PPEncode program.


PPEncode Online Tool is a powerful solution designed for encoding text using the PPEncode algorithm.  This tool offers a streamlined interface, enabling users to easily encode and decode text, ensuring confidentiality and efficient transmission of information. Whether for protecting critical data or optimizing information transfer, it simplifies the process with its user-friendly platform.

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.

Beaufort Cipher, is a polyalphabetic substitution cipher that is similar to the Vigenère cipher, except that it enciphers characters in a slightly different manner.

Four-Square Cipher encrypts pairs of letters (like playfair), which makes it significantly stronger than substitution ciphers etc. since frequency analysis becomes much more difficult.
