The Digital Signature Algorithm (DSA) is a public-key cryptosystem and Federal Information Processing Standard for digital signatures, based on the mathematical concept of modular exponentiation and the discrete logarithm problem.
On 32-bit systems only, installing drivers that are not validated with Microsoft is possible after agreeing to allow the installation at a prompt warning the user that the code is unsigned. For .NET (managed) code, there is an additional mechanism called Strong Name Signing that uses Public/Private keys and SHA -1 hash as opposed to certificates.
EJBCA is a full-featured, enterprise-grade, CA implementation developed in Java. It can be used to set up a CA both for internal use and as a service. (LGPL licensed) XiPKI, [36] CA and OCSP responder. With SHA-3 support, implemented in Java. (Apache licensed) XCA [37] is a graphical interface, and database. XCA uses OpenSSL for the underlying ...
Self-signed certificates can be created for free, using a wide variety of tools including OpenSSL, Java's keytool, Adobe Reader, wolfSSL and Apple's Keychain. They are easy to customize; e.g, they can have larger key sizes or hold additional metadata.
The protocol requires the server to present a digital certificate, proving that it is the intended destination. The connecting client conducts certification path validation , ensuring that: The subject of the certificate matches the hostname (not to be confused with the domain name ) to which the client is trying to connect.
The signer's public key consists of N and e, and the signer's secret key contains d. Used directly, this type of signature scheme is vulnerable to key-only existential forgery attack. To create a forgery, the attacker picks a random signature σ and uses the verification procedure to determine the message, m, corresponding to that signature. [32]
Java Authentication and Authorization Service, or JAAS, pronounced "Jazz", [1] is the Java implementation of the standard Pluggable Authentication Module (PAM) information security framework. [2] JAAS was introduced as an extension library to the Java Platform, Standard Edition 1.3 and was integrated in version 1.4.
Digital Signature Services (DSS) is an OASIS standard.. As part of a Technical Committee (TC), specialising in “signature services”, a “Core” specification was created by the international standardization organization OASIS in 2007.
