Apache::CryptHash is a Perl module with encrypted tokens for cookies. Creates an encrypted cookie-like string with a MAC (checksum) from a hash of critical and non-critical values. The MAC is created on only the critical values. Decryption will fail if the string has been altered and the MAC does not match when the string is decrypted. Particularly useful when using COOKIES and will do all the hard work for Apache::AuthCookie init() Create class reference and set passcode to the value returned by Sys::Hostname::hostname; my $c = Apache::CryptHash->init; # default passcode = hostname init takes an optional parameter my $c = Apache::CryptHash->init(no); $c->passcode(no} # will turn encryptation off # and put in Debug mode Optionally, the passcode or debug may be set by $c->passcode(no) # will turn encryptation off # and put in Debug mode $c->passcode(newpasscode); # change the passcode name & passcode Hash Header may be set to any string $c->name(some_string); # default Secret Just remember to obey the rules for allowed characters in cookie strings for both name & passcode encode() Generate an encrypted cookie-like value from a hash. Optional invarient values may be specified for a MAC $c->encode(%state, @mac_keys). Only the crypt secret and the mac_keys valuess are present in the MAC. What is returned is NAME:crypted_string (NAME.Debug:crypted_string) where $c->pascode(somename) (default Secret) decode($$$) Decrypt and generate state hash from the encrypted hash $c->decode($cookie,%state, @mac_keys); Return false if decode or MAC fails md5_hex($) Return the md5 hash of input string. md5_b64($) Return the md5 base 64 hash of input string. checkMAC $c = Apache::CryptHash->init(some password); $c->checkMAC(%state, @mac_keys) Does a comparison of the MAC in the %state vs the calculated value based on @mac_keys and returns a boolean result. Dont forget to set the passcode or the check will fail!.
