Intel® Cryptography Primitives Library Release Notes and System Requirements

Where to Find the Release

You can get the latest version of Intel® Cryptography Primitives Library as part of the Intel® oneAPI Toolkit, or as a Stand-Alone download.

If you have Priority Support for Intel® oneAPI Toolkit or any other oneAPI toolkit (i.e. an unexpired free license or a paid license with active support at the time of the build date for this product release), you can download the installer by logging in to Intel® Registration Center and selecting the appropriate product. You may need to create an account and/or register your product.

New in this Release

2026.0

Improvements and Changes

• Introduced ML-DSA and Intel® Local Manageability Service (Intel® LMS) (key&sign) post-quantum algorithms 

• Introduced PKCS#5 and new DRBG algorithms 

• Improved performance for SHA3 and ML-KEM algorithms on Intel® Xeon 6 with P-cores 

• Introduced support for Intel® Advanced Vector Extensions 10 (Intel® AVX10) and Intel® Advanced Performance Extensions (Intel® APX) code path 

• ML-KEM key generation, encapsulation and decapsulation were optimized with Intel® Advanced Vector Extensions 512 (Intel® AVX-512) instructions. 

• Added RSA partial key setting functions to enable incremental construction of RSA keys by setting individual components separately. 

• Extended ippsRSAVerify_PKCS1v15_rmf function to support pre-hashed message verification. 

Fixed Issues

• Eliminated branching depending on the GHASH value from the AES-GCM internal precomputation kernel. 

• Added more precise input parameters validation for multi-buffer functions (mbx_sm3_msg_digest_mb16, mbx_sm3_update_mb16, mbx_exp_mb8 and mbx_exp{1024,2048,3072,4096}_mb8). 

• Fixed multi-buffer library installation paths to use configurable variables instead of hardcoded paths for separate library builds. 

• Added initialization checks for static variables in methods regulating hashing and arithmetic over GF(q) to optimize multi-call usage scenarios. 

• Fixed issue with ippsHashUnpack_rmf and ippsHMACUnpack_rmf, which  could cause segmentation faults in some scenarios. 

Known Issues and Limitations

Details known issues with Description, Impact and workaround or resolution status.

2026.0

• ippsXMSSSign() and ippsXMSSKeyGen() API were not validated with Constant-time execution tests due to a limitation of the testing methodology, so the resistance to side-channel attacks cannot be guaranteed for this API. This limitation will be eliminated in one of the next product releases by changing the testing methodology 

• ippsXMSSKeyGen(), ippsMLKEM_KeyGen() and ippsMLKEM_Encaps() API by default works with RDRAND-based Pseudo Random Number Generator (PRNG). If this instruction is not available on a target CPU, a third-party PRNG should be provided to this API, see more details in the functions documentation. 

System Requirements

Supported Architectures and Terminology - Intel® 64 Architecture refers to systems based on IA-32 architecture processors which have 64-bit architectural extensions (like Intel® Core™ architecture processors, running a 64-bit operating system such as Microsoft Windows* 10 x64 or a Linux* "x86_64" variant).

Note: Minor releases (e.g., 2026.1) automatically inherit all OS requirements from the base major release (2026.0).Only operating systems marked with (+) are newly added in that minor release, and those marked with (–) are removed. Asterisks(**) indicates Deprecations. All others remain unchanged and are not duplicated in the table.

Hardware Requirements

Supported Operating Systems

Software Requirements

• Supported  IDEs and compilers 
  • Intel® oneAPI DPC++/C++ Compiler 2025.0 for Linux* OS and later 
  • Microsoft Visual Studio* 2022, 2026 

Support Deprecated

Support Removed 

• The code paths m7 (Intel® SSE3) and w7 (Intel® SSE2) are deprecated and removed from the merged build of Intel® Cryptography Primitives Library in the future releases, including 1cpu headers and libraries. 

• Removed support for fips_selftest_ippsRSASignVerify_PKCS1v15_rmf_get_size_keys and fips_selftest_ippsRSASignVerify_PKCS1v15_rmf_get_size.
