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 added in v1.9.1

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.
