They are hereby released under the GNU Public License V2. hash.c this contains an implementaion of the CDP hash and a trivial implementation of a double-barrelled SHA1-driver. both are in the public domain. sha1.c sha1.h these files came from courier-imap by Sam Varshavchik and are available under the GNU Public License V2. ec_crypt.c ec_crypt.h ec_curve.c ec_curve.h ec_field.c ec_field.h ec_param.c ec_param.h ec_vlong.c ec_vlong.h these files came from a long lost version of Pegwit that was placed into the public domain by George Barwood. They may contain code written by Paulo S.L.M. Barreto, or Vincent Rijmen. The precalculated tables in ec_field.c were altered for the build process, and because I abhor typing mixed-case functions, I ran the files through the following filter: $ perl -p -i -e 's/(cp|vl|gf|ec)([A-Z][a-zA-z]+)/$1."_".lc($2)/seg;' There may have been other changes. they are all in the public domain.
