$ pip install pyreadline

  • hsms - HSM sim that accepts UnsignedSpend objects and produces signatures, full or partial
  • hsmgen - generate secret keys
  • hsmpk - show public keys for secret keys
  • hsmmerge - merge signatures for a multisig spend
  • qrint - convert binary to/from qrint ascii

For testing & debugging:

  • hsm_test_spend - create a simple test UnsignedSpend multisig spend
  • hsm_dump_sb - debug utility to dump information about a SpendBundle
  • hsm_dump_us - debug utility to dump information about an UnsignedSpend

  • poser_verify - proof of secret exponent request verifier
