PHP T-Encryption

T-Encryption is a single file simple encryption class for PHP

If you use this encryption class, you can encrypt such as

1. String
2. File (Image, PDF)

I coded this encryption classes because so many a news about Indonesian government's data are stolen by hackers and leak to the internet. I hope you enjoy this class. coded with love by Teguh Rijanandi for everyone and if you see any error or bug you can feel free to open new issue or you can collaborate with me use pull request. Thanks

Note :

• WE NEVER STORE ANY DATA / FILE FROM YOU
• T means is Teguh (from my first letter name)

<?php
require_once 't_encrypt.php';
$masterpassword = "beautiful_system";

return t_encrypt::setPassword($masterpassword)
                ->encrypted_string(__DIR__ . "/example/encrypted_string.txt")

                ->print();

// Results :
// mendoan

Function explanation

You can set a master password for encryption and decryption proccess use ::setPassword function like this

$t_encrypt = t_encrypt::setPassword($masterpassword)

Note : You must choose only one encryption and decryption function

Encryption function

Set Input

1. You can set input as string use this function

$t_encrypt = $t_encrypt->input('mendoan')

2. You can set input as POST file use

$t_encrypt = $t_encrypt->input($_FILES['file'])

3. Or you can set input as file path use

$t_encrypt = $t_encrypt->input("/Users/mymac/Downloads/Resume_Teguh Rijanandi.docx.pdf")

Display Output

1. You can print output as string (PHP echo) use

$t_encrypt = $t_encrypt->print();

2. You can return the string (PHP Return) use

$t_encrypt = $t_encrypt->show();

3. or you can save as file use you can type for your files extension here but we prefer to save as txt file

$t_encrypt = $t_encrypt->saveAsFile(__DIR__ . "/example/encrypted_pdf.txt");

Decryption function

Set input

1. You can put encrypted string like this

$t_encrypt = $t_encrypt->encrypted_string("M7J1nJ3i3o2pP5rBvvDVBtTTi4kqPbpmrpmNUWf5FtVi1gLULg8y4jqCvmniabpnmR1izphuXCEo/fgUtIgMmKZ9+O0aW6ev8Jff9SOwGkA=") // mendoan

2. or you can put encrypted file here

$t_encrypt = $t_encrypt->encrypted_string(__DIR__ . "/example/encrypted_image.txt")

Display Output

1. You can print as string (PHP echo, image stream or pdf stream) use

$t_encrypt = $t_encrypt->print();

for example i was stream a pdf file in postman

and stream a image file in postman

2. You can return the string (PHP Return) use

$t_encrypt = $t_encrypt->show();

for example i will show to you a base64 image code in a postman

3. or you can save as file use you can type for your files extension here

$t_encrypt = $t_encrypt->saveAsFile(__DIR__ . "/example/decrypted_image.jpg");

// or

$t_encrypt = $t_encrypt->saveAsFile(__DIR__ . "/example/decrypted_text.txt");

For other code sample, you can read in encrypt_sample.php and decrypt_sample.php in this repository. And you can see encrypted and decrypted file in example folder. Thanks
