These APIs were first introduced into 1.1.0, and we intend to continue to support them moving forward in future versions. However they will not be backported to the 1.0.2 branch. We do not add new features to a stable branch. In 1.0.2 you must use the options SSL_OP_NO_SSLv3, SSL_OP_NO_TLSv1, SSL_OP_NO_TLSv1_1 and SSL_OP_NO_TLSv1_2 via the SSL_CTX_set_options() or SSL_set_options() functions. > > 2) > There are a set of APIs to set/get security level wherein each level > supports a set of cipher suites.

Kindly provide your comments. You can set the security level via the cipher string using the special cipher string command "@SECLEVEL". For example to set all default ciphersuites at security level 2 or above you can use: "DEFAULT:@SECLEVEL=2" Matt -- openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
