Discreet Log Contracts Oracle library (Go)

This library allows you to easily build oracles for use in Discreet Log Contracts using Go.

For a step-by-step instruction on how to build an oracle using this library, please see TUTORIAL.md

See the examples repository for more examples using this library. Feel free to contribute any examples you created by submitting a pull request to the samples repository.

# Functions

ComputeSignature

ComputeSignature Computes the signature for an arbitrary message based on two private scalars: The one-time signing key and the oracle's private key.

ComputeSignaturePubKey

ComputeSignaturePubKey calculates the signature multipled by the generator point, for an arbitrary message based on pubkey R and pubkey A.

GenerateNumericMessage

GenerateNumericMessage returns a zero-padded message for numeric values, LIT expects numeric oracle values to be 256-bit.

GenerateOneTimeSigningKey

GenerateOneTimeSigningKey will return a new random private scalar to be used when signing a new message.

LoadKeyFromFileArg

LoadKeyFromFileArg opens the file and returns the key.

LoadKeyFromFileInteractive

LoadKeyFromFileInteractive opens the file 'filename' and presents a keyboard prompt for the passphrase to decrypt it.

PublicKeyFromPrivateKey

PublicKeyFromPrivateKey derives the public key to a private key.

ReadKeyFile

ReadKeyFile returns an 32 byte key from a file.

SaveKeyToFileArg

saves a 96 byte key (three points) to a file, encrypting with pass.

SaveKeyToFileInteractive

saves a 32 byte key to file, prompting for passphrase.
