# git.sa-roci.de/oss/go_encryption

An extensible encryption package with an implementation for AES-128Bit en-/decryption functionality.

``` golang
type IEncryptionProvider interface {
    // SetEncryptionKey allows to modify the encryption key.
    SetEncryptionKey(key []byte)

    // SetContext allows to modify the encryption context.
    SetContext(context []byte) (err error)

    // Encrypt tries to encrypt the given binary with the appropriate cipher.
    Encrypt(binary []byte) (encrypted []byte, err error)

    // EncryptData returns the given data as JSON in encrypted form.
    EncryptData(data interface{}) (encrypted []byte, err error)

    // EncryptToFile saves the given data to the given filepath as JSON in encrypted form.
    EncryptToFile(data interface{}, filepath string) (err error)

    // Decrypt tries to decrypt the given binary with the appropriate cipher.
    Decrypt(binary []byte) (decrypted []byte, err error)

    // DecryptData tries to decrypt the given binary and to unmarshal the resulting JSON to the target interface.
    DecryptData(binary []byte, target interface{}) (err error)

    // DecryptData tries to decrypt the content of the file specified and to unmarshal the resulting JSON to the target interface.
    DecryptFile(path string, target interface{}) (err error)
}
