trezor-crypto tools

Set of small utilities using the trezor-crypto library.

xpubaddrgen

xpubaddrgen reads job specification from stdin in format:

<jobid> <xpub> <change> <from> <to>

and prints the results to stdout in format:

<jobid> <index> <address>

Example input:

It will print <jobid> error when there was an error processing job jobid.

It will print error when it encountered a malformed line.

mksecptable

mksecptable computes the points of the form (2*j+1)*16^i*G and prints them in the format to be included in secp256k1.c. These points are used by the fast ECC multiplication.

It is only meant to be run if the scalar_mult algorithm changes.
