CheckDataHash compares a slice of byte data with a hash using SHA-256.

HashPassword compares a plain-text password against a byte hash of a password hashed using the Bcrypt algorithm.

Decrypt uses AES-256 to decrypt the provided ciphertext and produce a newly allocated byte slice of the plaintext contents.

Encrypt uses AES-256 to encrypt the provided plaintext and produce a newly allocated byte slice of ciphertext.

HashData produces a byte hash of the provided data using the SHA-256 hashing algorithm.

HashPassword produces a byte hash of the provided password using the Bcrypt algorithm.

LoadSalt verifies that an existing byte slice only contains saltlen bytes.

NewDerivedKey uses the PBKDF2 key derivation algorithm to create a 256-bit key that can be used by the AES algorithm for encrypting and decrypting data.

NewPassword verifies the provided string value meets the criteria for a password and then wraps it in the Password type to indicate the string has been validated.

NewRandomKey uses a cryptographically strong random generator to create a 256-bit key that can be used by the AES algorithm for encrypting and decrypting data.

NewSalt creates a new slice containing saltlen bytes.

HashCost is the cost used by the Bcrypt algorithm when hashing a password.

Iterations is the number of iterations used when generating a key with PBKDF2.

KeyLength is the length of the key generated by PBKDF2 for encrypting data.

MaxPasswordLength is the maximum number of bytes a password can contain.

MinPasswordLength is the minimum number of characters that must be contained in a user-provided password.

SaltLength is the length of the salt used by PBKDF2 when generating a key.

DataHash is a hash of arbitrary data using SHA-256 represented as a 32-byte slice of bytes.

Key is the slice of keylen bytes used to encrypt data with AES-256.

PassHash is a hash of a password performed by Bcrypt represented as a slice of bytes.

Password is a user-provided string that has been validated and meets all criteria for a password.

Salt is the slice of saltlen bytes used when generating a key from a user-provided password.
