Passwords are secured using HMAC-512. HMAC (Hash-based Message Authentication Code) is a MAC defined in RFC2104 and FIPS-198 and constructed using a cryptographic hash algorithm.

Data is secured using AES-CBC. AES (Advanced Encryption Standard) is a symmetric block cipher standardized by NIST . It has a fixed data block size of 16 bytes. Its keys can be 128, 192, or 256 bits long.
