The OpenSSL Management Committee announced a change in the versioning scheme. Due to this change, the major number of the next major version would have been doubled, since the OpenSSL FIPS module already occupied this number. Therefore the decision was made to skip the OpenSSL 2.0 version number and continue with OpenSSL 3.0 .
Software versioning is the process of assigning either unique version names or unique version numbers to unique states of computer software. Within a given version number category (e.g., major or minor), these numbers are generally assigned in increasing order and correspond to new developments in the software.
The first part, ASN.1 type CertificationRequestInfo, consists of a version number (which is 0 for all known versions, 1.0, 1.5, and 1.7 of the specifications), the subject name, the public key (algorithm identifier + bit string), and a collection of attributes providing additional information about the subject of the certificate. The attributes ...
In cryptography, X.509 is an International Telecommunication Union (ITU) standard defining the format of public key certificates. [1] X.509 certificates are used in many Internet protocols, including TLS/SSL, which is the basis for HTTPS, [2] the secure protocol for browsing the web.
Several versions of the TLS protocol exist. SSL 2.0 is a deprecated [27] protocol version with significant weaknesses. 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]
PKCS #12 files are usually created using OpenSSL, which only supports a single private key from the command line interface. The Java keytool can be used to create multiple "entries" since Java 8, but that may be incompatible with many other systems. [8] As of Java 9 (released 2017-09-21), PKCS #12 is the default keystore format. [9] [10]
OpenSSL version 3.0 includes extensive CMP support in C. [3] Bouncy Castle API offers a low-level CMP support in Java and C#. [4] RSA BSAFE Cert-J provides CMP support. cryptlib provides CMP support. EJBCA, a CA software, implements a subset [4] [5] of the CMP functions. Nexus Certificate Manager supports CMP.
The newest version of CMS (as of 2024) is specified in RFC 5652 (but also see RFC 5911 for updated ASN.1 modules conforming to ASN.1 2002 and RFC 8933 and RFC 9629 for updates to the standard). The architecture of CMS is built around certificate-based key management, such as the profile defined by the PKIX working group .
