I then encrypted the private key itself using regular mcrypt with the human-memorizable key of my choice and converted it to ACSII using base64_encode. 2 and earlier uses a Trust Evaluation Agent (TEA) feature without terminating certain TLS/SSL handshakes as specified in the SSL_CTX_set_verify callback function's documentation, which allows remote attackers to bypass extra verification within a custom application via a crafted certificate. The SSL context used for talking directly to SSL servers is freed and recreated on reconfigure. When using this feature, the OpenSSL library will attempt to locate certificate files based on a hash of their name and serial number. This means that a private key is used to sign requests, rather than the OAuth token secret/consumer secret. Welcome to the wolfSSL product documentation.
