While Internet Explorer may still work with some AOL products and services, it's no longer supported by Microsoft and can't be updated. Because of this, we recommend you download a supported browser for a more reliable and secure experience online.
A delegated credential is a short-lived key (from a few hours to a few days) that the certificate's owner delegates to the server for use in TLS. It is in fact a signature: the certificate's owner uses the certificate's private key to sign a delegated public key, and an expiration time.
The Certification Authority Browser Forum, also known as the CA/Browser Forum, is a voluntary consortium of certification authorities, vendors of web browsers and secure email software, operating systems, and other PKI-enabled applications that promulgates industry guidelines governing the issuance and management of X.509 v.3 digital certificates that chain to a trust anchor embedded in such ...
Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network, such as the Internet.The protocol is widely used in applications such as email, instant messaging, and voice over IP, but its use in securing HTTPS remains the most publicly visible.

Its issuer and subject fields are the same, and its signature can be validated with its own public key. Validation of the trust chain has to end here. If the validating program has this root certificate in its trust store, the end-entity certificate can be considered trusted for use in a TLS connection. Otherwise, the end-entity certificate is ...
When you make a purchase on AOL, we'll only finish the transaction if your browser supports SSL. As you enter your credit card number, SSL encodes it so it's transmitted in a format that prevents eavesdropping or data theft. When it's received by our secure server, your credit card number is never transmitted over the Internet again.
A server implements an HSTS policy by supplying a header over an HTTPS connection (HSTS headers over HTTP are ignored). [1] For example, a server could send a header such that future requests to the domain for the next year (max-age is specified in seconds; 31,536,000 is equal to one non-leap year) use only HTTPS: Strict-Transport-Security: max-age=31536000.
