Converting a KEM with known associated public key into a signature efficiently
Alice challenges Bob to generate a signature S for a challenge input D. … *PS: Assume a hash based signature scheme is not allowed. I'm curious about generic and efficient ways to convert asymmetric KEMs into signatures, not trying to recreate SPHINCS+. …

Can Ed25519 signature be used as a base for ChaCha20 secret key?
A signature is not intended to be secure key material and can not be used as such. … Notably, this method of key derivation will fail if the signature scheme used allows recovering the public parameters from a valid signature(which is a property for some signature schemes).
*** Why the …
