go-crypto GoDoc

go-crypto is the cryptographic package adapted for Tendermint's uses

Importing it

import "github.com/tendermint/go-crypto"

Binary encoding

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

JSON Encoding

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

Example Amino:JSON encodings:

crypto.PrivKeyEd25519     - {"type":"954568A3288910","value":"EVkqJO/jIXp3rkASXfh9YnyToYXRXhBr6g9cQVxPFnQBP/5povV4HTjvsy530kybxKHwEi85iU8YL0qQhSYVoQ=="}
