|Hello Tomas,
|
|thank you for your response! I am aware of that ED25519 only supports
|the block operation. I also tried to implement that, but it seems to
|only call the update variant. Is there a way to "enforce" the use of the
|block operation in the provider? There seems to be a parameter for that,
|but I could not find the correct usage of that.
EVP_DigestSignInit + EVP_DigestSign does that.
See Ed25519(7ssl) (it is *so* cool that the documentation has
become so much better!):
The PureEdDSA instances do not support the streaming mechanism of other
signature algorithms using, for example, EVP_DigestUpdate(). The
message to sign or verify must be passed using the one‐shot
EVP_DigestSign() and EVP_DigestVerify() functions.
*My* problem is that it does not seem automatizable, ie, you there
is no interface which says which way to go. I had
if(!EVP_DigestSignInit(mdcp->mdc_md_ctx, NIL, mdcp->mdc_md->md_md, NIL, kp->k_key) &&
!EVP_DigestSignInit(mdcp->mdc_md_ctx, NIL, NIL, NIL, kp->k_key)){
which "does that" (at least today), but is hacky.
