[Shawn K. Quinn]

This is a weekly posting showing daily summary signatures made by
the PGP timestamping service stamper.itconsult.co.uk for the week
whose dates are shown below.
Stamper provides both digital timestamping and email proof of
posting certificates.
Old: Signature Packet(tag 2)(276 bytes)
Ver 2 - old
Sig type - Signature of a canonical text document(0x01).
Creation time - Sat Jul 1 22:05:03 CDT 2017
Key ID - 0x81959DB570B61F81
Pub alg - RSA Encrypt or Sign(pub 1)
Hash alg - MD5(hash 1)
Hash left 2 bytes - 3d 31
RSA m^d mod n(2039 bits) - ...
-> PKCS-1

Are there still people using PGP 2.x in 2017? Modern GnuPG versions will
not recognize MD5 signatures at all, and for good reason, per Wikipedia

As of 2010, the CMU Software Engineering Institute considers MD5
"cryptographically broken and unsuitable for further use" .

To me, there's no point in publishing all these signatures "in order to
add weight to the trustworthiness of the service" because the hash
algorithm upon which the signatures are based has been considered broken
for several years, completely undermining any trustworthiness that might
have been there to begin with.
