Usage:
sigsum-debug help
Outputs a usage message.
sigsum-debug genkey
Outputs a new private key.
sigsum-debug pubkey
Reads a private key from stdin and output its public key.
sigsum-debug hashkey
Reads a public key from stdin and output its key hash.
sigsum-debug hashleaf -k PRIVATE_KEY [-s SHARD_HINT]
Reads data from STDIN and outputs a leaf hash.
-k, --private-key Private key to sign with
-s, --shard-hint Shard hint to use (Default: 0)
sigsum-debug sign -k PRIVATE_KEY [-s SHARD_HINT]
Reads data from STDIN and outputs a signature.
-k, --private-key Private key to sign with
-s, --shard-hint Shard hint to use (Default: 0)
sigsum-debug cosign -w WIT_PRIV -l LOG_PUB
Reads an ASCII signed tree head from STDIN and outputs a cosignature.
-w, --witness-priv Witness private key to sign with
-l, --log-pub Log public key to verify signed tree head
