I\'m looking to store some fairly sensitive data using PHP and MySQL and will be using some form of reversible encryption to do so since I need to get the data back out in plain text for it to be of a
For a Lisp class, we were given a simple row transposition cipher homework, which I tried to solve in Haskell, too. Basically, one just splits a string into rows of length n, and then transposes the r

It seems that PHP\'s openssl_sign and openssl_verify functions perform hashing of the data before signing, due to size restrictions, so I\'ve tried emulating this on the command line.
If I set a timestamp开发者_运维技巧 with signing, what happens? What if I don\'t set? Is it essential? Why is it recommended?Timestamping is used to specify time when the digital signature is made. T
