A form of cryptography where one key and algorithm is used to encrypt ... use, a public key. But the key to decrypt the data would remain secret, held only by Bob, a private key. Diffie and ...

We've also come to understand the NSA can also decrypt some HTTPS and SSH whenever it needs to. The attacks are commonly used on implementations of the Diffie-Hellman important exchange algorithm ...

Servers that use the Diffie-Hellman key exchange and TLS 1.2 and below are considered vulnerable. DTLS is also impacted. TLS 1.3 is considered safe. But despite having the capability to decrypt ...

The Diffie-Hellman ... encryption, or public-key cryptography. The far-ranging and long-lasting impact of this development is impossible to exaggerate. Not only is the algorithm still in use ...

But the Logjam flaw would allow an attacker to downgrade the encryption to a level that can be easily cracked. The Diffie-Hellman algorithm, in order to be secure, would use 2048-bit prime numbers ...
