E-Mail Encryption: S/MIME (X.509) vs (Open)PGP

Both standards are based on a asymmetric encryption (private/public keys). From a practical point of view, S/MIME is already supported by most e-mail clients (e.g. Outlook, Thunderbird), whereas PGP plug-ins have to be installed explicitly. On the other hand, PGP is more flexible and allows for encryption of arbitrary information, e.g. files, and can be operated not just with a hierachical trust model but also with a Web-of-Trust approach (which has advantages for private users).

You can find my S/MIME as well as my PGP certificates/keys below.

S/MIME certificates

Please click on the following link to download ralph.schlenk@gmx.de.der, my private S/MIME e-mail certificate. If you need the S/MIME certificate for my business e-mail address, please download ralph.schlenk@nokia.com.der.

While e-mail clients already trust the certification authority of my private S/MIME certificate, you need to install (and explicitly trust) the root certificate of my business certificate. The required certificates can be found at http://services.support.alcatel-lucent.com/PKI/.

Bitcoin Address

Bitcoin is a decentralized digital currency ("cryptocurrency") that enables instant payments to anyone in the world. If the necessary precautions are taken (Tor, Bitcoin laundry), money transfers are pretty anonymous.
