• Return encrypted data as Base64, quoted-printable, or hex-encoded strings.
• Hash strings or binary data using SHA1, MD2, MD5, HAVAL, SHA384, or SHA512.
• Public-key encryption with digital certificates.
• Create and verify digital signatures.
• Pre-convert Unicode strings to ANSI (single-byte/char) before encrypting.
• Pre-convert Unicode strings to any charset before encrypting, compressing, or hashing.
