CSP provides a generic implementation of the BCCSP interface based on wrappers. It can be customized by providing implementations for the following algorithm-based wrappers: KeyGenerator, KeyDeriver, KeyImporter, Encryptor, Decryptor, Signer, Verifier, Hasher. Each wrapper is bound to a goland type representing either an option or a key.

func New Uses

func New(keyStore bccsp.KeyStore) (*CSP, error)

func (*CSP) AddWrapper Uses

func (csp *CSP) AddWrapper(t reflect.Type, w interface{}) error

AddWrapper binds the passed type to the passed wrapper. Notice that that wrapper must be an instance of one of the following interfaces: KeyGenerator, KeyDeriver, KeyImporter, Encryptor, Decryptor, Signer, Verifier, Hasher.

func (*CSP) Decrypt Uses

func (csp *CSP) Decrypt(k bccsp.Key, ciphertext []byte, opts bccsp.DecrypterOpts) (plaintext []byte, err error)

Decrypt decrypts ciphertext using key k. The opts argument should be appropriate for the primitive used.

func (*CSP) Encrypt Uses

func (csp *CSP) Encrypt(k bccsp.Key, plaintext []byte, opts bccsp.EncrypterOpts) ([]byte, error)

Encrypt encrypts plaintext using key k. The opts argument should be appropriate for the primitive used.

func (*CSP) GetHash Uses

func (csp *CSP) GetHash(opts bccsp.HashOpts) (h hash.Hash, err error)

GetHash returns and instance of hash.Hash using options opts. If opts is nil then the default hash function is returned.

func (*CSP) GetKey Uses

func (csp *CSP) GetKey(ski []byte) (k bccsp.Key, err error)

GetKey returns the key this CSP associates to the Subject Key Identifier ski.

func (*CSP) Hash Uses
