AWS said that the name "s2n" stands for signal to noise as a nod "to the almost magical act of encryption—disguising meaningful signals, like your critical data, as seemingly random noise". [2] In 2022 AWS renamed it from s2n to s2n-tls. [5] It has been the subject of several external reviews as well as penetration testing. [6]
To provide the server name, RFC 4366 Transport Layer Security (TLS) Extensions allow clients to include a Server Name Indication extension (SNI) in the extended ClientHello message. This extension hints to the server immediately which name the client wishes to connect to, so the server can select the appropriate certificate to send to the clients.
SSL 3.0 (1996) and TLS 1.0 (1999) are successors with two weaknesses in CBC-padding that were explained in 2001 by Serge Vaudenay. [28] TLS 1.1 (2006) fixed only one of the problems, by switching to random initialization vectors (IV) for CBC block ciphers, whereas the more problematic use of mac-pad-encrypt instead of the secure pad-mac-encrypt ...
Secure Hypertext Transfer Protocol (S-HTTP) is an obsolete alternative to the HTTPS protocol for encrypting web communications carried over the Internet. It was developed by Eric Rescorla and Allan M. Schiffman at EIT in 1994 [1] and published in 1999 as RFC 2660 Netscape's dominance of the browser market led to HTTPS becoming the de facto method for securing web communications.
Settings may be in a different location in each email client, though the AOL server and port settings will always be the same. For additional questions specific to the email client, check the manufacturer’s website. Manufacturers cannot answer questions about your AOL Mail settings, or your AOL username or password.
Network Security Services (NSS) is a collection of cryptographic computer libraries designed to support cross-platform development of security-enabled client and server applications with optional support for hardware TLS/SSL acceleration on the server side and hardware smart cards on the client side.
