A number of the folks I work with have been using Cryptopad for a while now. I hadn't messed with the code in quite a while, so I figured I'd clean things up a bit, add a few more algorithms, etc., etc. At any rate, here it is...hopefully you'll find it useful. I'd appreciate it any constructive comments.

It should be noted that to avoid complications with disp +laying meta-characters, the encrypted output is escaped via MIME::Bas +e64. Starting with v2.02, Acme::Playwright is included as one of the +encryption algorithms. Please be advised that this is not, nor should + it be considered to be strong encryption. Rather, it is simple text +obfuscation in the form of a play. CryptoPad supports multiple rounds of encryption. For example, it is p +ossible to encrypt your data with TripleDES, then with AES, then with + RC4. Decryption would then be possible in the reverse order. The nam +e of the encryption algorithm is shown to facilitate this. It is impo +rtant to note that knowing which encryption algorithm was used in no +way diminishes the security of the encryption. The Message Digests are generated with SHA1, MD5, MD4, and MD2 Message + Digest algorithms by RSA Security Inc., RIPEMD-160 by Hans Dobbertin +, Antoon Bosselaers, and Haval256 by Bart Preneel, of Katholieke Univ +ersiteit Leuven, and Yuliang Zheng, Josef Pieprzyk, and Jennifer Sebe +rry..

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
