Boost DES and 3DES ECB Performance with NXP’s MMCAU in wolfSSL

Starting in wolfSSL 5.7.4, it is now supported to use NXP’s MMCAU hardware accelerator to handle DES and 3DES ECB Crypto Operations. This addition to the MMCAU hardware port can be seen in PR #7960.

The MMCAU can be used to speed up other cryptography algorithms in wolfSSL like:

  • AES – 128/192/256
  • MD5
  • SHA – 1
  • SHA – 256

To see more about our support with NXP hardware check out our NXP hardware page or if you want to evaluate wolfSSL 5.7.4 you can download that here!

What Algorithms Will Your Customers Need by 2035?

As we approach the end of the year, it is a good time to reflect on where you are in your transition to post-quantum cryptography. Have you started? Do you have a plan in place? If so, what does your timeline look like? Most importantly, does it meet the requirements of your customers? If you are not sure what those requirements are, then you will find the following document very enlightening.

NIST (National Institute of Standards and Technology) recently published a document known as IR 8547.

It is titled “Transition to Post-Quantum Cryptography Standards” and gives detailed assessments of the threat from quantum computers including explanations of cryptographic components in software and communications infrastructure and migration to post-quantum cryptography considerations. The document is only 20 pages and the language is very accessible even to the layman; no Ph.D required.

The most notable guidance within this document is section 4 titled “Towards a PQC Standards Transition Timeline”. It begins by referencing National Security Memorandum 10 (NSM-10) which was issued by the Whitehouse. Directly quoting from it:

“Any digital system that uses existing public standards for public?key cryptography, or
that is planning to transition to such cryptography, could be vulnerable to an attack by a
Cryptographically Relevant Quantum Computer (CRQC). To mitigate this risk, the United
States must prioritize the timely and equitable transition of cryptographic systems to
quantum-resistant cryptography, with the goal of mitigating as much of the quantum
risk as is feasible by 2035.”

To summarize the rest of the section, ECDSA, EdDSA, RSA, FFDH, and ECDH are all disallowed for usage by 2035. By then, their post-quantum counterparts – ML-DSA, SLH-DSA, LMS, XMSS, and ML-KEM – should be used in their place. 2035 is only 10 years away. How does that fit in with your product development cycle and cryptographic certification timelines?

Perhaps there will be some exceptions, but likely those will be hard to come by, expensive, and require long processing time as they will be on a case-by-case basis. The better situation to be in is to simply be ready and have completed your migration to post-quantum cryptography.

Want to get started? We at wolfSSL are very proud that we already have post-quantum algorithms implemented and you can try them out in wolfSSL, wolfSSH, wolfMQTT and wolfBoot! Go ahead and get started to better understand how these new algorithms will affect your products and your customer’s user experience!

Post-Quantum KEM TLS 1.3 Security Level Fix

Recently, in our 5.7.4 release we fixed a bug in our TLS 1.3 post-quantum key exchange implementation. The bug was that when users wanted to use post-quantum Kyber (ML-KEM) for key establishment in TLS, the security level the user picked was being ignored by the wolfSSL library.

The fix can be found here.

With this simple fix, you can be assured that you are negotiating post-quantum key establishment at the desired security level. This is true for both Kyber (ML-KEM) on its own as well as hybridized with ECDH.

Users building with –enable-kyber and enabling PQC cipher suites with TLS 1.3 connections are recommended to update the version of wolfSSL used.

Big thanks to Daniel Correa for finding and reporting the bug.

wolfCLU Initial s_server Support

We have added initial support for the s_server command to wolfCLU! This exciting new feature supports handling basic TLS connections leveraging the best tested cryptography from the wolfSSL library. It is a quick way to set up simple TLS connection tests. So far the arguments available are :

```
./wolfssl s_server
	-help
	-port <+int>
    	Port to listen on.


	-key 
    	only PEM can be used.


	-cert 
    	only PEM can be used.


	-noVerify
    	Disable client cert check.


	-CAfile 
    	only PEM can be used.


	-version 
    	SSL version [0-4], SSLv3(0) - TLS1.3(4))


	-naccept <+int>
    	Number of times to accept.(default 1)


	-www
    	The response is in HTML format.


	-readyFile 
    	Create Ready file for external monitor.
```

wolfCLU Tests

Throughout the last development cycle, we have increased the test coverage for wolfCLU. This includes many different types of tests done with continuous integration. One of the tests expanded was involving -fsanitize=address builds on every code addition by updating the GitHub actions used. Another was expanding the unit test for the new features added including the ML-DSA (Dilithium support). This is all part of a never ending effort to always be improving on the quality of wolfCLU. Feel free to reach out to us at support@wolfSSL.com with any troubles encountered when using wolfCLU.

wolfCLU dgst Command

The `dgst` command of wolfCLU saw support for some new arguments with the latest release. Support for `-inform` was added, giving the flexibility to choose if the incoming file is in DER or PEM format. Before only PEM formatted inputs were handled and the application would gracefully error out if a DER input had been given. An example of using this new argument would be the following `wolfssl dgst -inform DER -sign private.ec.der -sha512 -out test.wc.sig test.bin`. To see all of the options available for the `dgst` command uses the `-h` flag, i.e. `wolfssl dgst -h`.

wolfCLU PEM Key Enhancement With Sign and Verify

Enhancements were made to wolfCLU for using PEM formatted keys with sign and verify operations. Previously, the sign and verify commands only expected DER formatted keys. This addition was made for all supported algorithms: RSA, ECC, and ED25519. It can be used with the flag -inform. An example would be `wolfssl rsa -inkey priv.key -inform PEM -sigfile signature.bin -in sign-this.txt -out result`. This new enhancement helps make it easier to quickly generate a signature of a file. No longer have the restriction on the format of keys used and the hassle of converting between the two.

wolfCLU RSA Command

The `rsa` command with wolfCLU just got better! Now there is support for `-pubin` and `-pubout` options. This facilitates loading in a RSA public key only and printing out just the public version of the key. Very useful for cases such as signature verification where you may only have the public part of the key, or for printing out the public version of an RSA key to distribute to others. The expanded support follows the same naming as the OpenSSL command line utility, making it easy to interchange the command line utility being used.

wolfCLU Adds Support for Post Quantum ML-DSA (Dilithium) Signatures!

We have added support for creating and verifying signatures with ML-DSA. This new feature was introduced in wolfCLU release 0.1.6 and can be seen in the handy help message by running `wolfssl -h`. There are a couple of options available to be passed to the new `dilithium` command to increase the flexibility for tuning performance versus security strength.
