OpenPGP Message Format ( RFC 4880 ) well defines key structure and wire formats (openpgp packets). Thus when I looked for public key network (SKS) server setup, I quickly found pointers to dump files in said format for bootstrapping a key server. I did not feel like experimenting with Python and instead opted for Go and found http://code.google.com/p/go.crypto/openpgp/packet library that has comprehensive support for parsing openpgp low level structures. I've downloaded the SKS dump, verified it's MD5SUM hashes (lolz), and went ahead to process them in Go. With help from http://github.com/lib/pq and database/sql, I've written a small program to churn through all the dump files, filter for primary RSA keys (not subkeys) and inject them into a database table. The things that I have chosen to inject are fingerprint, N, E. N & E are the modulus of the RSA key pair and the public exponent. Together they form a public part of an RSA keypair. So far, nothing fancy. Ne...
