Summary0001278: CAcert PGP key is using outdated and insecure crypto algorithms (DSA/1024 bit)
DescriptionThe CAcert PGP signing key is currently a 1024 bit DSA key. 1024 Bit discrete logarithm based algorithms are not considered secure these days and DSA itself is a very questionable algorithm, because it easily can completely break when used with bad randomness.

I suggest CAcert creates a new PGP signing key with 4096 bit RSA and defaults to SHA512-signatures (both for key self-signatures and for signing other keys).
