Hi everybody,
I try to verify a xml file which was signed with ecdsa-sha1.
I alredy read to SignatureValue from the xmlfile. which is.

are you _really_ sure that this is a ecdsa-with-something signature ?
Your data starts with 0xEF,0x6E... but a ecdsa signature is a
asn.1 sequence of two asn.1 integers and hence must begin with 0x30 ...
hmm, actually I was wrong. According to rfc 4050 the xml ecdsa-*
signature value is simply the concatenation of the two signature
value without the asn.1 der encoding ...
OpenSSL has no function to handle this signature format directly.
