Spring Security is a Java/Java EE framework that provides authentication, authorization and other security features for enterprise applications. The project was started in late 2003 as 'Acegi Security' (pronounced Ah-see-gee / ɑː s iː dʒ iː /, whose letters are the first, third, fifth, seventh, and ninth characters from the English alphabet, in order to prevent name conflicts [2]) by Ben ...
The Secure Remote Password protocol (SRP) is an augmented password-authenticated key exchange (PAKE) protocol, specifically designed to work around existing patents. [1]Like all PAKE protocols, an eavesdropper or man in the middle cannot obtain enough information to be able to brute-force guess a password or apply a dictionary attack without further interactions with the parties for each guess.
Because many users re-use passwords for multiple sites, the use of a salt is an important component of overall web application security. [14] Some additional references for using a salt to secure password hashes in specific languages or libraries (PHP, the .NET libraries, etc.) can be found in the external links section below.
Time-based one-time password (TOTP) is a computer algorithm that generates a one-time password (OTP) using the current time as a source of uniqueness. As an extension of the HMAC-based one-time password algorithm (HOTP), it has been adopted as Internet Engineering Task Force (IETF) standard RFC 6238. [1]
Transport Layer Security Secure Remote Password (TLS-SRP) ciphersuites are a set of cryptographic protocols that provide secure communication based on passwords, using an SRP password-authenticated key exchange. There are two classes of TLS-SRP ciphersuites: The first class of cipher suites uses only SRP authentication.

The simplest example of a challenge-response protocol is password authentication, where the challenge is asking for the password and the valid response is the correct password. An adversary who can eavesdrop on a password authentication can authenticate themselves by reusing the intercepted password. One solution is to issue multiple passwords ...
HMAC-based one-time password (HOTP) is a one-time password (OTP) algorithm based on HMAC. It is a cornerstone of the Initiative for Open Authentication (OATH). HOTP was published as an informational IETF RFC 4226 in December 2005, documenting the algorithm along with a Java implementation. Since then, the algorithm has been adopted by many ...
