I recently switched my GnuPG key. The previous key – which is still in place for now (no revocation send out yet) – was 0x5DFAB3ECCDBA2FDB and was a 1024 bit DSA key. The new one, 0x2EDD52403B68AF47, is a 4096 bit RSA key. It also has the following preferences:
gpg> showpref [ultimate] (1). Sven Vermeulen <email@example.com> [ultimate] (2) Sven Vermeulen <firstname.lastname@example.org> Cipher: AES256, AES192, AES, CAST5, 3DES Digest: SHA512, SHA384, SHA256, SHA224, SHA1 Compression: BZIP2, ZLIB, ZIP, Uncompressed Features: MDC, Keyserver no-modify
The new key’s fingerprint is as follows:
gpg> fpr pub 4096R/0x2EDD52403B68AF47 2013-09-16 Sven Vermeulen
Primary key fingerprint: 7264 9F85 E8F1 6F6A 4B68 1102 2EDD 5240 3B68 AF47
A signed key transition statement can be found on my Gentoo development page; the document is signed with both of my keys (the old one and new one).
