> 2. The RSA key strength is only 1280 bits.
This reminds me that in france, unless cryptography is not used for authentication, it is considered a military weapon, and civil usage is restricted in its key strength. Above a certain strength, you technically have to give your key to the government !!...!!!
I don't have a source, but fr.wiki [1] says that in 1999, the government allowed for 128 bit keys to be publicly used without depositing it to the government. It also says that PGP was illegal in france until 1996 (considered a war weapon of category 2, whatever that means).
So I wouldn't be surprised if it were illegal over here to use key strengths above 2048 for end to end encryption in france...
