Functions

func NewAesDecryptionStream

func NewAesDecryptionStream(key []byte, iv []byte) cipher.Stream

NewAesDecryptionStream creates a new AES encryption stream based on given key and IV. Caller must ensure the length of key and IV is either 16, 24 or 32 bytes.

func NewAesEncryptionStream

func NewAesEncryptionStream(key []byte, iv []byte) cipher.Stream

NewAesEncryptionStream creates a new AES description stream based on given key and IV. Caller must ensure the length of key and IV is either 16, 24 or 32 bytes.

func NewChaCha20Stream

func NewChaCha20Stream(key []byte, iv []byte) cipher.Stream

NewChaCha20Stream creates a new Chacha20 encryption/descryption stream based on give key and IV. Caller must ensure the length of key is 32 bytes, and length of IV is either 8 or 12 bytes.
