implementation of linkable ring signatures using elliptic curve crypto in go
go ^1.10
go get github.com/noot/ring-go
the branch unique is an implementation of unique ring signatures (no key images). the branch linkable contains an implementation of linkable ring signatures.
the algorithm including Sign() and Verify() (and Link() for linkable) is located in ring/ring.go.
to use the cli, perform the following:
cd $GOPATH/github.com/noot/ring-go
go build && go install
ring-go [flags] [opts]
cli flags:
ring-go --gen generate a new public-private key pair and save the files in the ./keystore directory.
ring-go --sign /path/to/pubkey/dir /path/to/privkey.priv message.txt sign a message inside message.txt using the private key at privkey.priv and the public keys inside the specified folder. note: inside /path/to/pubkey/diryou can only have pubkeys in their 64-byte format as generated by this cli. this will generate an output signature file and save it in the ./signatures directory.
ring-go --verify /path/to/signature.sig verify a signature file generated by this program.
