1 This is the same test as rsa-pkcs1-sha256.pem except the SPKI has been encoded
2 using a non-minimal length for the outtermost SEQUENCE.
3
4 Under DER, the tag-length-value encodings should be minimal and hence this shoul d fail.
5
6 Specifically the SPKI start was changed from:
7 30 81 9f
8 To:
9 30 82 00 9f
10
11 (the length of 0x9F is being expressed using 2 bytes instead of 1)
