For example, attackers might compromise a certificate authority, and then mis-issue certificates for a web origin. To combat this risk, the HTTPS web server serves a list of “pinned” public key hashes valid for a given time; on subsequent connections, during that validity time, clients expect the server to use one or more of those public ...

The Microsoft Windows platform specific Cryptographic Application Programming Interface (also known variously as CryptoAPI, Microsoft Cryptography API, MS-CAPI or simply CAPI) is an application programming interface included with Microsoft Windows operating systems that provides services to enable developers to secure Windows-based applications using cryptography.
In 2013, RSA contributed the latest draft revision of the standard (PKCS#11 2.30) to OASIS to continue the work on the standard within the newly created OASIS PKCS11 Technical Committee. [3] The following list contains significant revision information: 01/1994: project launched; 04/1995: v1.0 published; 12/1997: v2.01 published; 12/1999: v2.10 ...

The CAPI/CSP architecture had its origins in the era of restrictive US government controls on the export of cryptography. Microsoft's default or "base" CSP then included with Windows was limited to 512-bit RSA public-key cryptography and 40-bit symmetric cryptography, the maximum key lengths permitted in exportable mass market software at the time.
The publishing of TLS 1.3 and DTLS 1.3 obsoleted TLS 1.2 and DTLS 1.2. Note that there are known vulnerabilities in SSL 2.0 and SSL 3.0. In 2021, IETF published RFC 8996 also forbidding negotiation of TLS 1.0, TLS 1.1, and DTLS 1.0 due to known vulnerabilities.
Convert counter to an octet string C of length 4 with the primitive I2OSP: C = I2OSP (counter, 4) C = int. to_bytes (counter, 4, "big") # b. Concatenate the hash of the seed Z and C to the octet string T: T = T || Hash (Z || C) T += hash_func (seed + C). digest counter += 1 # 4. Output the leading l octets of T as the octet string mask. return ...
