Decrypt takes a JSON-encoded ciphertext object encrypted using Encrypt and tries to decrypt it using passphrase.

Encrypt takes a passphrase and plaintext, and returns a JSON object containing ciphertext and the details necessary to decrypt it.

EncryptWithCustomKDFParameters takes a passphrase, the plaintext and a KDF parameter level (Legacy, Standard, or OWASP), and returns a JSON object containing ciphertext and the details necessary to decrypt it.

Marshal encrypts the JSON encoding of v using passphrase.

MarshalWithCustomKDFParameters encrypts the JSON encoding of v using passphrase.

Unmarshal decrypts the data using passphrase and unmarshals the resulting plaintext into the value pointed to by v.

Legacy defines legacy scrypt parameters (N:2^15, r:8, p:1).

OWASP defines OWASP recommended scrypt parameters (N:2^17, r:8, p:1).

Standard defines standard scrypt parameters which is focusing 100ms of computation (N:2^16, r:8, p:1).

KDFParameterStrength defines the KDF parameter strength level to be used for encryption key derivation.
