Functions

func Contains

func Contains(slice []string, value string) bool

Contains will check a given []string to see if a value is inside of it, and returns true if so and false if not.

func CreateHash

func CreateHash(toHash []byte) string

CreateHash will return a hashed string of a given string

func Decrypt

func Decrypt(ciphertext []byte, key []byte) (plaintext []byte, err error)

Decrypt decrypts data using 256-bit AES-GCM. This both hides the content of the data and provides a check that it hasn't been altered. Expects input form nonce|ciphertext|tag where '|' indicates concatenation.

func Encrypt

func Encrypt(plaintext []byte, key []byte) (ciphertext []byte, err error)

Encrypt encrypts data using 256-bit AES-GCM. This both hides the content of the data and provides a check that it hasn't been altered. Output takes the form nonce|ciphertext|tag where '|' indicates concatenation.

func NewEncryptionKey

func NewEncryptionKey() []byte

NewEncryptionKey generates a random 256-bit key for Encrypt() and Decrypt().

func ValidateHostName

func ValidateHostName(name string) (bool, error)

ValidateHostName will use regex to determine if the given URL or IP address is valid.
