Usage

Install

et -u go.mozilla.org/cose

Signing a message

See example/sign.go and run it with:

 run example/sign.go
lengths of integers r and s (256 and 256) do not match the key length 255
age signature (ES256): 043685f99421f9e80c7c3c50d0fc8266161d3d614aaa3b63d2cdf581713fca62bb5d2e34d2352dbe41424b31d0b4a11d6b2d4764c18e2af04f4520fbe494d51c

Verifying a message

See example/verify.go and run it with:

 run example/verify.go
lengths of integers r and s (256 and 254) do not match the key length 254
age signature (ES256): 9411dc5200c1cb67ccd76424ade09ce89c4a8d8d2b66f2bbf70edf63beb2dc3cbde83250773e659b635d3715442a1efaa6b0c030ee8a2523c3e37a22ddb055fa
age signature verified

Development

Running tests:

1. Install rust and cargo

2. On OSX: brew install nss nss then in sign_verify_cose_rust_cli_test.go add NSS_LIB_DIR to cmd or -L /usr/local/opt/nss/lib to RUSTFLAGS e.g. cmd.Env = append(os.Environ(), "NSS_LIB_DIR=/usr/local/opt/nss/lib", "RUSTFLAGS=-A dead_code -A unused_imports")

3. If you already have dep and golint commands installed, run make install-godep install-golint

4. Run go test
