Adding this to the !crypto group… ♻ @dennisgut NTRU public key crypto released to the free and open source community #RSA and #ECC are the two most common public-key crypto systems in use today. At the 2013 Black Hat conference, researchers declared that the math for cracking #encryption algorithms could soon become so efficient that it will render the RSA crypto #algorithm obsolete. http://www.net-security.org/secworld.php?id=15997

The Debian administration article mentions a phased transition to a new key over 3 months. Getting your new key signed by the old one. Attending key signings to get it integrated into the WoT, and contacting people who's keys you've signed to check they are still in control of their keys so you can recertify them with your new key.

@boneidol Thanx! I've done mostly that, except for the descending order of SHA strength (/me fixes that now). And since my key is DSA, I guess I should generate a new keypair. If I don't revoke the old key, but expire it so that its Web of Trust stays intact, does that weaken the WoT? !crypto

Checked my prefs in GnuPG with "gpg --edit-key bjonkman" then "showprefs"; SHA1 was the only digest algorithm listed. Issued command "setpref" to set all algorithms to default, but SHA1 was listed first. Issued command "setpref CAST5 3DES IDEA AES256 AES192 AES SHA256 SHA384 SHA512 SHA224 ZLIB BZIP2 ZIP Uncompressed MDC" to remove SHA1, but GnuPG added it back, now listed last. !crypto https://www.schneier.com/blog/archives/2013/11/microsoft_retir.html

Here's an example ...."An attacker intercepts the following ciphertext (hex encoded): 20814804c1767293b99f1d9cab3bc3e7 ac1e37bfb15599e5f40eef805488281d He knows that the plaintext is the ASCII encoding of the message "Pay Bob 100$" (excluding the quotes). He also knows that the cipher used is CBC encryption with a random IV using AES as the underlying block cipher. Show that th…

https://www.coursera.org/course/crypto course is starting again in January ... I crammed and passed it in 2 weeks. I quite enjoyed it, and got a good understanding of the !crypto primitives I use every day... Because I crammed it missed out some of the optional programming questions. So I may well do it again.
