Virge::Enigma

Used to encrypt/decrypt data, and produce hashes., _(*1)

Encrypt

Encryption used mcrypt to encrypt/decrypt data. Default set to RIJNDAEL_128 but can be changed as needed., _(*2)

$myString = "secrets";
$key = "password";
$encrypted = Enigma::encrypt($myString, $key);
Enigma::decrypt($encrypted, $key); //secrets

Hash

Hashing uses the hash_hmac function and supports all alogrithms returned by hash_algos();, _(*3)

$passwordHash = Enigma::hash('mypassword', 'salt');

Can also be used without input, in which case it will generate a hash of the current microtime, _(*4)

$randomhash = Enigma::hash();

Encrypt File

Encryption of a file takes in an input file and an output file. The input file is read in blocks of 1MB, encrypted, and written out to the output file., _(*5)

Likewise, decryption will take an input file (the encrypted file) and an output file, will read the encrypted file line by line., _(*6)

$inputFile = "./test.txt";

$outputFile = "./encrypted.txt";

$decryptedFile = "./decrypted.txt";

Enigma::encryptFile($inputFile, $outputFile, "secret");

Enigma::decryptFile($outputFile, $decryptedFile, "secret");

if(Enigma::md5File($inputFile) !== Enigma::md5File($decryptedFile)) {
    die("File hashes do not match");
}
