Topic: CTR-DRBG

Hi

What is the supported DRBG implementations exist in the wolfSSL?
Is 256-bit CTR AES DRBG supported and exist in your master branch?
How can I configure the wolfssl library to be compiled with this DRBG? (256 AES Key and 128 status/counter)?

Thanks,
Mohammad

Re: CTR-DRBG

Hi mohammad.abomokh,

Thank you for using the wolfSSL forums.

From the available DRBG implementations outlined in NIST special publication 800-90A wolfSSL has only implemented the Hash_DRBG.

http://csrc.nist.gov/publications/nistp … 00-90A.pdf

Hash_DRBG     - SUPPORTED in wolfSSL
HMAC_DRBG    - NOT SUPPORTED in wolfSSL
CTR_DRBG       - NOT SUPPORTED in wolfSSL
Dual_EC_DRBG - NOT SUPPORTED in wolfSSL

Please let us know if you have any questions on this.

Warm Regards,

Kaleb

Re: CTR-DRBG

Hi mohammad,

wolfSSL has many features in progress and/or under review for implementation. I am unsure if CTR-DRBG is one of those items. I have requested that one of our business managers reach out to you directly to discuss future projects and get a better understanding of your need for CTR-DRBG.


Best Regards,
