That's just the way ECDSA and DSA signatures work. Yes the ASN.1 encoding
factors in but mostly it's just the way the math goes. The signature is a
tuple (r,s) where r and s are mod n and n is fixed per curve. r and s are
always smaller than n, normally around the same size as n, but can also be

I am glad someone is asking this question.

I am glad someone is asking this question.
I sign the same data with same private key and sometimes the signature is 63
and sometimes it is 64 but overall the verification works for each
anyhow.
