README.md

crypto

crypto is the cryptographic package adapted for Tendermint's uses

Importing it

To get the interfaces, import "github.com/tendermint/tendermint/crypto"

For any specific algorithm, use its specific module e.g. import "github.com/tendermint/tendermint/crypto/ed25519"

If you want to decode bytes into one of the types, but don't care about the specific algorithm, use import "github.com/tendermint/tendermint/crypto/amino"

Binary encoding

For Binary encoding, please refer to the Tendermint encoding spec.

JSON Encoding

crypto .Bytes() uses Amino:binary encoding, but Amino:JSON is also supported.

Example Amino:JSON encodings:
