| The key, message, and signature come from Example 1 of: |
| ftp://ftp.rsa.com/pub/rsalabs/tmp/pkcs1v15sign-vectors.txt |
| |
| (The algorithm DER was synthesized to match, and the signature enclosed in a BIT STRING). |
| |
| It uses an RSA key with modulus length of 1024 bits, PKCS#1 v1.5 padding, and |
| SHA-1 as the digest. |
