Functions ¶
Types ¶
type AesCrypter ¶
type AesCrypter struct {
// contains filtered or unexported fields
}
AesCrypter implement CoreCrypter interface using AES-128/192/256 depending on the given key length
func NewAesCrypter ¶
func NewAesCrypter(key []byte) *AesCrypter
NewAesCrypter create a new AesCrypter
func (*AesCrypter) Decrypt ¶
func (ac *AesCrypter) Decrypt(dest, src []byte) error
Decrypt decrypt cipher
func (*AesCrypter) Encrypt ¶
func (ac *AesCrypter) Encrypt(dest, src []byte) error
Encrypt encrypt plain It's important to remember that ciphertexts must be authenticated (i.e. by using crypto/hmdc) as well as being encrypted in order to be secure. authentication will be done outside core crypter, (in content encrypter) to include file ID and block No.
func (*AesCrypter) EncryptWithIV ¶
func (ac *AesCrypter) EncryptWithIV(dest, src []byte, iv []byte)
EncryptWithIV encrypt plain using given IV
func (*AesCrypter) LenAfterDecrypted ¶
func (ac *AesCrypter) LenAfterDecrypted(cipherLen int) int
LenAfterDecrypted decrypted info length given cipher with specific length
func (*AesCrypter) LenAfterEncrypted ¶
func (ac *AesCrypter) LenAfterEncrypted(plainLen int) int
LenAfterEncrypted encrypted info length given plain info with specific length
type CoreCrypter ¶
type CoreCrypter interface {
LenAfterEncrypted(plainLen int) int
LenAfterDecrypted(cipherLen int) int
// Encrypt encrypt src to dest
Encrypt(dest, src []byte) error
// Decrypt decrypt src to dest
Decrypt(dest, src []byte) error
}
CoreCrypter defines interface for core crypt module
func NewCoreCrypter ¶
func NewCoreCrypter(mode int, key []byte) CoreCrypter
NewCoreCrypter return a new CoreCrypter
type DesCrypter ¶
type DesCrypter struct {
// contains filtered or unexported fields
}
DesCrypter implement CoreCrypter interfdce
func NewDesCrypter ¶
func NewDesCrypter(key []byte) *DesCrypter
NewDesCrypter create a new DesCrypter
func (*DesCrypter) Decrypt ¶
func (dc *DesCrypter) Decrypt(dest, src []byte) error
Decrypt decrypt cipher
func (*DesCrypter) Encrypt ¶
func (dc *DesCrypter) Encrypt(dest, src []byte) error
Encrypt encrypt plain It's important to remember that ciphertexts must be authenticated (i.e. by using crypto/hmdc) as well as being encrypted in order to be secure. authentication will be done outside core crypter, (in content encrypter) to include file ID and block No.
func (*DesCrypter) EncryptWithIV ¶
func (dc *DesCrypter) EncryptWithIV(dest, src []byte, iv []byte)
EncryptWithIV encrypt plain using given IV
