output signature into provided [u8]

stevedw opened this issue a year ago · 2 comments

Hi,
Is it possible to add a method to output the sig directly into a provided mut slice rather than return a sig for use cases where it would be better not to have to do a copy fromt he result each time?

Or if it exists I seme to be missing it in the docs.

There is no corresponding API on BigUint which provides this functionality to my knowledge

Also note that as of #220 both pkcs1v15::Signature and pss::Signature are wrappers for BigUint, if you're worried about an extra round trip to bytes.

That said, without an upstream API we can't implement this. I'd suggest opening an upstream issue.
