openssl: add generated asm code
12 years ago
TITLE ../openssl/crypto/bn/asm/x86-mont.asm
IF @Version LT 800
ECHO MASM version 8.00 or later is strongly recommended.
ENDIF
Revert "deps: downgrade openssl to v1.0.0f" After much investigation it turns out that the affected servers are buggy. user-service.condenastdigital.com:443 in particular seems to reject large TLS handshake records. Cutting down the number of advertised ciphers or disabling SNI fixes the issue. Similarly, passing { secureOptions: constants.SSL_OP_NO_TLSv1_2 } seems to fix most connection issues with IIS servers. Having to work around buggy servers is annoying for our users but not a reason to downgrade OpenSSL. Therefore, revert it. This reverts commit 4fdb8acdaef4c3cb1d855e992ada0e63fee520a6.
