Going from KEM to Signatures
Is there a known efficient way to generically convert a secure KEM into a signature scheme? I'm looking for a method that doesn't devolve to turning the KEM into an OWF and then building a hash based signature scheme. I am aware that you can use a secure KEM to …

question about web crypto subtle ecdh shared secrets
hello everybody, is there any way to generate an ecdh key with javascript in a browser and with c on a backend? how are the common secrets calculated? im trying to get a edch shared secret in a browser and on a backend without using subtle on the backend itself? …

ML-DSA secret norms?
I was performing vivisection of an implementation of ML-DSA and noticed that the L2 norms of the secret vectors were longer than I had anticipated. My understanding (which could be incorrect) was that for a secret to be short enough it should fall within 0 ≤ |x|\_l2 ≤ B, where …
Thoughts and Opinions About SQIsign?
What are your thoughts and opinions about SQIsign, the post-quantum digital signature?
When using Groth16, is it really needed to change both G₂ points of the public & private inputs in the trusted setup for avoiding public input forgery ?
First remember ᴇɪᴘ‒197 only allow to check if a set of pairings is equal to 1 in Fp^(12) and not to compare equalities like in Zcash which is why the equations below are different and would worth downvotes on a cryptographic sub as a result… # For those who don’t …
