NAME

Crypt::Mimetic::TEA - Tiny Encryption Algorithm

DESCRIPTION

This module is a part of Crypt::Mimetic.

This modules uses TEA to encrypt blocks of bytes, so DecryptFile needs @info containing generic-blocks-length and last-block-length (padlen) to know how decrypt a file. EncryptString and DecryptString always encrypt/decrypt a string as a single block.

PROCEDURAL INTERFACE

string ShortDescr (): Return a short description of algorithm
boolean PasswdNeeded (): Return true if password is needed by this algorithm, false otherwise. ('TEA' return always true)
($len,$blocklen,$padlen,[string]) EncryptFile ($filename,$output,$algorithm,$key,@info): Encrypt a file with TEA algorithm. See Crypt::Mimetic::EncryptFile.
string EncryptString ($string,$algorithm,$key,@info): Encrypt a string with TEA algorithm. See Crypt::Mimetic::EncryptString.
[string] DecryptFile ($filename,$output,$offset,$len,$algorithm,$key,@info): Decrypt a file with TEA algorithm. See Crypt::Mimetic::DecryptFile.
string DecryptString ($string,$algorithm,$key,@info): Decrypt a string with TEA algorithm. See Crypt::Mimetic::DecryptString.

NEEDED MODULES

This module needs: Error::Mimetic Crypt::Tea

KNOWN BUGS

Seems to be quite slow.
