Simple ROT13 Premium

Simple ROT13 Premium is an utility allowing to cipher a text using ROT13 or L33T ROT13 algorithm, and use other cipher algorithms as MDx and SHA-x.

Current version : 1.6, May 15, 2015

Simple ROT13 Premium

The following algorithms are available:

  • MD2
  • MD4
  • MD5
  • ROT13
  • ROT13 (L33T)
  • ROT47
  • SHA-1
  • SHA-224
  • SHA-256
  • SHA-384
  • SHA-512

ROT13 is a simple cipher which shift each letter from the text to cipher of 13 characters.

L33T ROT13 replace vowels with digits, and is a one-way ciphering algorithm.

ROT47 works the same manner than ROT13, but uses more characters (letters, digits, special characters).

MDx and SHA-x are one-way hash algorithms.

Simple ROT13 Premium is available on the App Store for 1.99 $ as an universal app for iPhone, iPod touch and iPad.

Multiple budgets, multiple options
