Types

type KeyStore

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

KeyStore is an implementation of encid.KeyStore backed by a SQLite database.

func New

func New(ctx context.Context, filename string, newcipher func([]byte) (cipher.Block, error)) (*KeyStore, error)

New creates a new SQLite-backed keystore using the given file. The newcipher function takes a key and returns a cipher for encrypting and decrypting.

If the keystore is new (i.e., contains no keys), the version number of the keystore is set to 2. If the keystore is non-empty and was created before v1.5.0 of this module, its version will be 1. The version number controls whether the resulting encoded ids include a checksum. Version 1 ids are not compatible with version 2 ids.

func (*KeyStore) DecoderByID

func (ks *KeyStore) DecoderByID(ctx context.Context, id int64) (typ int, dec func(dst, src []byte), err error)

func (*KeyStore) EncoderByType

func (ks *KeyStore) EncoderByType(ctx context.Context, typ int) (id int64, enc func(dst, src []byte), err error)

func (*KeyStore) NewKey

func (ks *KeyStore) NewKey(ctx context.Context, typ, keysize int) (int64, error)

func (*KeyStore) Version added in v1.5.0
