openssl: add generated asm code
12 years ago
TITLE cast-586.asm
IF @Version LT 800
ECHO MASM version 8.00 or later is strongly recommended.
ENDIF
deps: downgrade openssl to v1.0.0f Several people have reported issues with IIS and Resin servers (or maybe SSL terminators sitting in front of those servers) that are fixed by downgrading OpenSSL. The AESNI performance improvements were nice but stability is more important. Downgrade OpenSSL from 1.0.1e to 1.0.0f. Fixes #5360 (and others).
