A small piece of PHP code that lets you encrypt and decrypt messages using various encyption methods.

This piece of code does not require any additional software or libraries to be installed, only incorporate it into your project and you are set to go.

NOTE: This is a simple PHP function that will encrypt and decrypt the message, before using it in production please research encryption a bit more in order to be safer.

Instructions:

In order to encrypt a message just use "encrypt_decrypt('encrypt', {your message}, {password})" and to decrypt you just use "encrypt_decrypt('decrypt', {encrypted message}, {password})".

Supported encryption methods: AES-128-CBC AES-128-CFB AES-128-CFB1 AES-128-CFB8 AES-128-CTR AES-128-ECB AES-128-OFB AES-128-XTS AES-192-CBC AES-192-CFB AES-192-CFB1 AES-192-CFB8 AES-192-CTR AES-192-ECB AES-192-OFB AES-256-CBC AES-256-CFB AES-256-CFB1 AES-256-CFB8 AES-256-CTR AES-256-ECB AES-256-OFB AES-256-XTS BF-CBC BF-CFB BF-ECB BF-OFB CAMELLIA-128-CBC CAMELLIA-128-CFB CAMELLIA-128-CFB1 CAMELLIA-128-CFB8 CAMELLIA-128-ECB CAMELLIA-128-OFB CAMELLIA-192-CBC CAMELLIA-192-CFB CAMELLIA-192-CFB1 CAMELLIA-192-CFB8 CAMELLIA-192-ECB CAMELLIA-192-OFB CAMELLIA-256-CBC CAMELLIA-256-CFB CAMELLIA-256-CFB1 CAMELLIA-256-CFB8 CAMELLIA-256-ECB CAMELLIA-256-OFB CAST5-CBC CAST5-CFB CAST5-ECB CAST5-OFB DES-CBC DES-CFB DES-CFB1 DES-CFB8 DES-ECB DES-EDE DES-EDE-CBC DES-EDE-CFB DES-EDE-OFB DES-EDE3 DES-EDE3-CBC DES-EDE3-CFB DES-EDE3-CFB1 DES-EDE3-CFB8 DES-EDE3-OFB DES-OFB DESX-CBC RC2-40-CBC RC2-64-CBC RC2-CBC RC2-CFB RC2-ECB RC2-OFB RC4 RC4-40 RC4-HMAC-MD5 SEED-CBC SEED-CFB SEED-ECB SEED-OFB
