cryptor

type Cryptor ¶

type Cryptor interface {
	// Encrypt source file and write encrypted content to destination file.
	Encrypt(ctx context.Context, sourceFile, destinationFile string) error
	// Decrypt source file and write decrypted content to destination file.
	Decrypt(ctx context.Context, sourceFile, destinationFile string) error
}

Cryptor provides sub-system to encrypt and decrypt files (backup mostly). Files are managed outside of cryptor. Implementations may not care about removal or creation of the provided files. Implementation must expect, that files could be large (bigger then RAM).
