Base85 Encode & Decode

ChaCha Cipher is a stream cipher designed by Daniel J. Bernstein. It is a variant of the Salsa stream cipher. Several parameterizations exist; 'ChaCha' may refer to the original construction, or to the variant as described in RFC-8439.

LS47 Cipher is a slight improvement of the ElsieFour cipher as described by Alan Kaminsky. It use 7x7 characters instead of original (barely fitting) 6x6, to be able to encrypt some structured information. It also describe a simple key-expansion algorithm, because remembering passwords is popular.

RC2 (also known as ARC2) is a symmetric-key block cipher designed by Ron Rivest in 1987. 'RC' stands for 'Rivest Cipher'.

Characters Escape & Unescape can escapes special characters in a string so that they do not cause conflicts, and unescapes Characters in a string that have been escaped.
