From 047500ae23a12469ce3e458c6a58a642716041b7 Mon Sep 17 00:00:00 2001 From: Rasmus Dahlberg Date: Sat, 23 Apr 2022 18:19:25 +0200 Subject: add drafty tool named sigsum-debug Meant to be used for debugging and tests only. Replaces cmd/tmp/* in log-go, expect for the DNS command which is redundant. Use `dig -t txt $domain_hint` to debug domain hints. --- cmd/sigsum-debug/leaf/sign/sign.go | 37 +++++++++++++++++++++++++++++++++++++ 1 file changed, 37 insertions(+) create mode 100644 cmd/sigsum-debug/leaf/sign/sign.go (limited to 'cmd/sigsum-debug/leaf/sign') diff --git a/cmd/sigsum-debug/leaf/sign/sign.go b/cmd/sigsum-debug/leaf/sign/sign.go new file mode 100644 index 0000000..348ae23 --- /dev/null +++ b/cmd/sigsum-debug/leaf/sign/sign.go @@ -0,0 +1,37 @@ +package sign + +import ( + "fmt" + "strings" + + "git.sigsum.org/sigsum-go/internal/fmtio" + "git.sigsum.org/sigsum-go/pkg/hex" + "git.sigsum.org/sigsum-go/pkg/types" +) + +func Main(args []string, optPrivateKey string, optShardHint uint64) error { + if len(args) != 0 { + return fmt.Errorf("trailing arguments: %s", strings.Join(args, ", ")) + } + data, err := fmtio.BytesFromStdin() + if err != nil { + return fmt.Errorf("read stdin: %w", err) + } + priv, err := fmtio.SignerFromHex(optPrivateKey) + if err != nil { + return fmt.Errorf("parse private key: %w", err) + } + + preimage := types.HashFn(data) + stm := types.Statement{ + ShardHint: optShardHint, + Checksum: *types.HashFn(preimage[:]), + } + sig, err := stm.Sign(priv) + if err != nil { + fmt.Errorf("sign leaf: %w", err) + } + + fmt.Printf("%s\n", hex.Serialize(sig[:])) + return nil +} -- cgit v1.2.3
