GnuPG and OTR are the two most widely supported standards for the encryption of e-mails and online chats respectively. Nevertheless, they are either not supported at all or not well enough supported by several popular pieces of software.
I therefore encourage everyone interested to pledge money to the following items on the Free Software crowdfunding platform BountySource:
- OTR encryption in Thunderbird chat
- PGP/MIME support for K-9 mail. K-9 mail is the best PGP-enabled mail client for Android. It cannot decipher e-mails very well that are sent with attachments from other clients, such as Thunderbird.
- OTR import and export for Jitsi. Jitsi is a popular Free Sotware instant messenger and telephony software. While it supports OTR encryption, one cannot yet easily import and export one’s cryptographic identity to also use it with other software.
- PGP support for Geary. Geary is an e-mail client for Linux which looks very promising.
