Functions ¶
func NewStreamDecrypter ¶
NewStreamDecrypter returns a new RC4 stream decrypter
Types ¶
type KeySizeError ¶
type KeySizeError int
KeySizeError represents an error when the RC4 key size is invalid. RC4 keys must be between 1 and 256 bytes long. This error occurs when the provided key does not meet these size requirements.
func (KeySizeError) Error ¶
func (k KeySizeError) Error() string
Error returns a formatted error message describing the invalid key size. The message includes the actual key size and the required size range for debugging.
type ReadError ¶
type ReadError struct {
Err error // The underlying error that caused the failure
}
ReadError represents an error when reading encrypted data fails. This error occurs when reading encrypted data from the underlying reader fails. The error includes the underlying error for detailed debugging.
type StdDecrypter ¶
type StdDecrypter struct {
Error error
// contains filtered or unexported fields
}
StdDecrypter represents an RC4 decrypter
func NewStdDecrypter ¶
func NewStdDecrypter(key []byte) *StdDecrypter
NewStdDecrypter returns a new RC4 decrypter
func (*StdDecrypter) Decrypt ¶
func (d *StdDecrypter) Decrypt(src []byte) (dst []byte, err error)
Decrypt decrypts src using RC4
type StdEncrypter ¶
type StdEncrypter struct {
Error error
// contains filtered or unexported fields
}
StdEncrypter represents an RC4 encrypter
func NewStdEncrypter ¶
func NewStdEncrypter(key []byte) *StdEncrypter
NewStdEncrypter returns a new RC4 encrypter
func (*StdEncrypter) Encrypt ¶
func (e *StdEncrypter) Encrypt(src []byte) (dst []byte, err error)
Encrypt encrypts src using RC4
type StreamDecrypter ¶
type StreamDecrypter struct {
Error error
// contains filtered or unexported fields
}
StreamDecrypter implements io.Reader interface for streaming RC4 decryption
func (*StreamDecrypter) Read ¶
func (d *StreamDecrypter) Read(p []byte) (n int, err error)
Read implements io.Reader interface
type StreamEncrypter ¶
type StreamEncrypter struct {
Error error
// contains filtered or unexported fields
}
StreamEncrypter implements io.WriteCloser interface for streaming RC4 encryption
func (*StreamEncrypter) Close ¶
func (e *StreamEncrypter) Close() error
Close implements io.Closer interface
func (*StreamEncrypter) Write ¶
func (e *StreamEncrypter) Write(p []byte) (n int, err error)
Write implements io.Writer interface
type WriteError ¶
type WriteError struct {
Err error // The underlying error that caused the failure
}
WriteError represents an error when writing encrypted data fails. This error occurs when writing encrypted data to the underlying writer fails. The error includes the underlying error for detailed debugging.
func (WriteError) Error ¶
func (e WriteError) Error() string
Error returns a formatted error message describing the write failure. The message includes the underlying error for debugging.
