AES CTR

More information on AES CTR, pronounced "counter":

» NIST's specification. (PDF file)

» RFC 3686, which describes, in alphabet soup essence, AES CTR 4 IPsec ESP. AES CTR "has many properties that make it an attractive encryption algorithm for high-speed networking. [...] Implementations MUST use AES CTR in conjunction with an authentication function, such as HMAC-SHA-1-96."

» WinZip uses AES CTR + HMAC-SHA1 in its eponymous product.
