Creates a text encryptor that performs no encryption. Useful for developer testing environments where working with plain text strings is desired for simplicity.
Creates an encryptor for queryable text strings that uses standard password-based encryption. Uses a 16-byte all-zero initialization vector so encrypting the same data results in the same encryption result. This is done to allow encrypted data to be queried against. Encrypted text is hex-encoded.
password | the password used to generate the encryptor's secret key; should not be shared |

salt | a hex-encoded, random, site-global salt value to use to generate the secret key |
Creates a standard password-based bytes encryptor using 256 bit AES encryption. Derives the secret key using PKCS #5's PBKDF2 (Password-Based Key Derivation Function #2). Salts the password to prevent dictionary attacks against the key. The provided salt is expected to be hex-encoded; it should be random and at least 8 bytes in length. Also applies a random 16 byte initialization vector to ensure each encrypted message will be unique. Requires Java 6.
