Revision 1.8, Sun Jan 15 23:05:32 2023 UTC (16 months ago) by djm
Branch: MAIN
CVS Tags: OPENBSD_7_5_BASE, OPENBSD_7_5, OPENBSD_7_4_BASE, OPENBSD_7_4, OPENBSD_7_3_BASE, OPENBSD_7_3, HEAD
Changes since 1.7: +1 -3 lines

update OpenSSH's Ed25519 code to the last version of SUPERCOP (20221122)
and change the import approach to the same one we use for Streamlined
NTRUPrime: use a shell script to extract the bits we need from SUPERCOP,
make some minor adjustments and squish them all into a single file.
