Using strong passwords lowers the overall risk of a security breach, but strong passwords do not replace the need for other effective security controls. The effectiveness of a password of a given strength is strongly determined by the design and implementation of the authentication factors (knowledge, ownership, inherence). The first factor is ...
e. Digest access authentication is one of the agreed-upon methods a web server can use to negotiate credentials, such as username or password, with a user's web browser. This can be used to confirm the identity of a user before sending sensitive information, such as online banking transaction history.
Time-based one-time password. 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] TOTP is ...
For the application developer, JAAS is a standard library that provides: a representation of identity ( Principal) and a set of credentials ( Subject) a login service that will invoke your application callbacks to ask the user things like username and password. It returns a new Subject. a service that tests if a Subject was granted a permission ...
Description. The input to the bcrypt function is the password string (up to 72 bytes), a numeric cost, and a 16-byte (128-bit) salt value. The salt is typically a random value. The bcrypt function uses these inputs to compute a 24-byte (192-bit) hash. The final output of the bcrypt function is a string of the form:
A one-time password ( OTP ), also known as a one-time PIN, one-time authorization code ( OTAC) or dynamic password, is a password that is valid for only one login session or transaction, on a computer system or other digital device. OTPs avoid several shortcomings that are associated with traditional (static) password-based authentication; a ...
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 ...
The Java Cryptography Extension ( JCE) is an officially released Standard Extension to the Java Platform and part of Java Cryptography Architecture (JCA). JCE provides a framework and implementation for encryption, key generation and key agreement, and Message Authentication Code (MAC) algorithms. JCE supplements the Java platform, which ...
