Thanks. I'm getting concerned though...
On this page, there is a message posted and signed by Wladimir:

https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2015-June/009045.html

Code:
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512

Hello,

Starting with 0.11.0rc3, SHA256SUMS.asc will be signed with the following key:

    pub   4096R/36C2E964 2015-06-24 Wladimir J. van der Laan (Bitcoin Core binary release signing key)
    Primary key fingerprint: 01EA 5486 DE18 A882 D4C2  6845 90C8 019E 36C2 E964

For gitian and commit signing I will keep using this key.

For some reason, when I try to verify this message with PGP (Symantec Encryption Desktop 10.3.0), using the same key, I signed **years** ago in my PGP keyring, and that still shows as verified, I am getting a mismatch:

Code:
*** PGP SIGNATURE VERIFICATION ***

*** Alert:    Signature did not verify. Message has been altered.

*** END PGP VERIFIED MESSAGE ***

The key signature matches! Is there some possible incompatibility between PGP and GPG? Some whitespace / line endings mismatch?
Given, that "state-sponsored" attackers are suspected to be a risk, I'm starting to get paranoid now!!! This is the first time I think I've ever seen verifications fail.

Can anyone else verify the signature on that message with Wladimir's key?
