Downloading electrum source and signature from https://electrum.org/#download:

Checking site with ssllabs:
https://www.ssllabs.com/ssltest/analyze.html?d=electrum.org

The site scores 80/100 on Key Exchange. Is the below 'WEAK' entries antyhing at all to be concerned about?

Code:
Cipher Suites (SSL 3+ suites in server-preferred order; deprecated and SSL 2 suites always at the end)
TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 (0xc030)   ECDH 256 bits (eq. 3072 bits RSA)   FS 256
TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 (0xc028)   ECDH 256 bits (eq. 3072 bits RSA)   FS 256
TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA (0xc014)   ECDH 256 bits (eq. 3072 bits RSA)   FS 256
TLS_DHE_RSA_WITH_AES_256_GCM_SHA384 (0x9f)   DH 1024 bits (p: 128, g: 128, Ys: 128)   FS   WEAK 256
TLS_DHE_RSA_WITH_AES_256_CBC_SHA256 (0x6b)   DH 1024 bits (p: 128, g: 128, Ys: 128)   FS   WEAK 256
TLS_DHE_RSA_WITH_AES_256_CBC_SHA (0x39)   DH 1024 bits (p: 128, g: 128, Ys: 128)   FS   WEAK 256

The only handshake simulation which had a match was:

Code:
OpenSSL 0.9.8y 	TLS 1.0 	TLS_DHE_RSA_WITH_AES_256_CBC_SHA (0x39)   FS 	256 

But that's an old OpenSSL version.

Further, I found ThomasV's pubkey here:

But as you can see, those are different, why?
