RUSTSEC-2026-0329 Auto-Reseeding HMAC-DRBG could panic for some output lengths

The automatically reseeding implementations of HMAC-DRBG would panic if called with a desired non-zero output length cleanly divisible by 65536, the maximum number of output bytes that can be generated before reseeding has to happen. Impact An application relying on libcrux-hmac-drgb to provide...

An issue was discovered in Mbed TLS before 2.28.9 and 3.x before 3.6.1, in which the user-selected algorithm is not used. Unlike previously documented, enabling MBEDTLS PSA HMAC DRBG MD TYPE does not cause the PSA subsystem to use HMAC DRBG: it uses HMAC DRBG only when MBEDTLS PSA CRYPTO EXTERNAL...

Proof that HMAC-DRBG has No Back Doors

New research: "Verified Correctness and Security of mbedTLS HMAC-DRBG," by Katherine Q. Ye, Matthew Green, Naphat Sanguansin, Lennart Beringer, Adam Petcher, and Andrew W. Appel. Abstract: We have formalized the functional specification of HMAC-DRBG NIST 800-90A, and we have proved its...
