In case you want to contact me securely, you can use following possibilities :

• PGP : my Key is signed by various people
  • Key fingerprint DA62 0DCB FEF6 3F00 A7B6 1D25 822E E70C D482 7E51
• SMIME 1 (for home (at) joel-hatsch.net) : my Key is signed by StartCom and should thus be validated out of the box by most of the mail agents.
  • Key fingerprint 224F 55F9 0722 F42C D5B3 00EC 28BE 5334 0759 2417
  • Validity : from 2014-12-01 through 2015-12-02
  • Restrictions of this free key is the limited bit size and used hashing algorithms
  • Furthermore though the key is generated locally within the browser (and not remotely at StartCom !), there is no possibility to influence the generation nor to provide a key generated through other ways
  • Nevertheless I am not aware of real security threats related to these
• SMIME 2 (for secure (at) joel-hatsch.net) : for the paranoids out there I have generated a high-security key, signed by my own Signing CA, which in turn is signed by my own Root CA
