The OpenSSL library implements the Secure Sockets Layer and Transport Layer Security protocols, as well as providing a large number of basic cryptographic functions. The Secure Sockets Layer protocol exists in two versions and includes a mechanism for negotiating the protocol version to be used. If the protocol is executed correctly, it is impossible for a client and server both capable of the newer version of the protocol (SSLv3) to end up using the older version of the protocol (SSLv2). In order to provide bug-for-bug compatibility with Microsoft Internet Explorer 3.02, a verification step required by the Secure Sockets Layer protocol can be disabled by using the SSL_OP_MSIE_SSLV2_RSA_PADDING option in OpenSSL. This option is implied by the frequently-used SSL_OP_ALL option.
