Subject: Adjust tests to "ECDSA raw/asn1 signature conversion methods"
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=refs%2Fchanges%2F92%2F307092%2F1;p=platform%2Fcore%2Ftest%2Fsecurity-tests.git

Adjust tests to "ECDSA raw/asn1 signature conversion methods"

If the ECDSA signature is presented in asn1 format, the first byte is always asn1 metadata,
it's better to change the last byte, which will always be signature data.
