| Name | Description |
|---|---|
| Aes | Symmetric AES-256-CBC encryption functions powered by OpenSSL. |
| AesCtr | Symmetric AES-256-CTR encryption functions powered by OpenSSL. |
| Cryptobase | Provides functionality common to Dcrypt's block ciphers. |
| Hash | An opaque 512 bit iterative hash function. |
| Mcrypt | Symmetric Mcrypt wrapper functions. |
| Otp | A simple one time pad encryption class designed to provide moderate security and high performance with low memory usage. Uses simple XOR operations to encrypt data with a key. The Otp::crypt() function is safer to run on pseuro-random input that needs to be obscured. |
| Pkcs7 | Provides PKCS #7 padding functionality. |
| Random | Fail-safe wrapper for mcrypt_create_iv (preferably) and openssl_random_pseudo_bytes (fallback). |
| Rc4 | An implementation of RC4 symmetric encryption. |
| Spritz | An implementation of Spritz symmetric encryption. |
| Str | Provides time-safe string comparison facilities, and safe string operations on systems that have mb_* function overloading enabled. |
| Support | Provides numeric data conversion helper functions. |
