IBM® z/OS® Version 2 Release 4 System SSL Cryptographic Module

FIPS 140-2 certificate #4618 · IBM Corporation · data as of 2026-10-21

IBM® z/OS® Version 2 Release 4 System SSL Cryptographic Module, from IBM Corporation, holds FIPS 140-2 certificate #4618 at overall level 1. The validation is historical: agencies may keep the module in existing systems but not buy it new. Below are its validation history, algorithm certificates and security policy, drawn from the NIST CMVP entry.

Historical. Moved to historical list due to sunsetting. Federal agencies may reference historical validations for existing systems only, not for new procurement.

Module description

Quoted from the NIST CMVP entry for this certificate.

z/OS® System SSL provides a rich set of C based application programming interfaces that allow applications to protect data using the SSL/TLS protocols and through PKCS#7 cryptographic messages. z/OS System SSL also enables applications to create and manage X.509 V3 certificates and keys within key database files and PKCS#11 tokens.
