Subject: Add SRP and PSK to disallowed CertificateRequest ciphersuites
X-Git-Tag: OpenSSL_1_1_0-pre1~326
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=b7fa1f989d0059ad7b992c11797f37f095d61204;p=oweals%2Fopenssl.git

Add SRP and PSK to disallowed CertificateRequest ciphersuites

There was a discrepancy between what ciphersuites we allowed to send a
CertificateRequest, and what ciphersuites we allowed to receive one. So
add PSK and SRP to the disallowed ones.
