The only reason why I put up this (home-)page is to encourage you to use PGP or GPG to encrypt your electronic mail. After all, lots of people prefer sending letters enclosed into envelopes over sending a post-card readable by anyone. Read here for some perspectives why one could/should use PGP/GPG.
When sending me an e-mail, encrypted mail is of course most certainly welcome!
If you want/need to get familiar with public-key crypto-systems, I recommend taking a closer look here. If you really want to get into the math behind public-key-crypto-systems, you could start with the RSA-algorithm.
Here are my public keys. Of course you can also get my keys from a keyserver via HTTP.
Before using a PGP public-key you should actually make sure whether the key really belongs to whom you think it should belong. E.g. you could call the person and verify the fingerprints.
If you want to send me e-mail, please chose any one of these:
bits DSA/El Gamal)
This one should be handled by all newer PGP versions > 5.x.
preferred -- 0x844F6301 (4096 bit
RSA-keys should be handled by every version of PGP.
0xE69B0F49 (1024 bit
Use this RSA-key if your PGP can't handle the big one.
0x73495D19 (768 bit RSA) Revocation Certificate
This key should not be used any longer!
