Subject: catcrypt.c, catsign.c: Shorten chunk sizes.
X-Git-Url: https://git.distorted.org.uk/u/mdw/catacomb/commitdiff_plain/f52f2db067dc1388b16ab00ddb53e26a381a6e3e?hp=f52f2db067dc1388b16ab00ddb53e26a381a6e3e

catcrypt.c, catsign.c: Shorten chunk sizes.

The chunks are written with a 16-bit length, so the maximum chunk size
is 2^16 - 1 = 65535.  Unfortunately, catsign tried to write 65536-byte
chunks, and catcrypt tried to cram a MAC tag in there too.  The result
is that chunk_write fails an assertion because the chunks are too big.

No idea why this ever worked before.
