Types

type Crypt 

type Crypt struct {
	// contains filtered or unexported fields
}

Crypt structure holds implementation of particular Key Management Service e.g. AWS KMS

func NewCrypt 

func NewCrypt(kms KMS) *Crypt

NewCrypt creates a new crypt with corresponding Key Management Service

func (*Crypt) DecryptFile 

func (c *Crypt) DecryptFile(inputPath, outputPath string) error

DecryptFile reads from the inputPath file or stdin if empty. Then decrypts content with corresponding Key Management Service. Plaintext is saved into outputPath file or print on stdout if empty.

func (*Crypt) EncryptFile 

func (c *Crypt) EncryptFile(inputPath, outputPath string) error

EncryptFile reads from the inputPath file or stdin if empty. Then encrypts content with corresponding Key Management Service. Ciphertext is saved into outputPath file or print on stdout if empty.

type KMS 

type KMS interface {
	Encrypt(plaintext []byte) ([]byte, error)
	Decrypt(ciphertext []byte) ([]byte, error)
}

KMS - Key Management Service interface abstracts common cryptographic operations. A KMS must be able to decrypt the data it encrypts.
