Hello,
I'm trying to make sense out of the various abbrevations used for the
SSL cipher suites listed by openssl ciphers.
I've googled, but found no explanation of what ECDHE is and how it
compares to ECDH.
I'm aware that ECDH stands for elliptic curve diffie hellman key
exchange (and I'm also
ECDHE is the E=Ephemeral version where you get a distinct DH key for
every handshake.
ECDH has a fixed DH key; one side of the handshake doesn't change from
one instance to the next.
ECDHE gives you forward secrecy; ECDH does not.
ECDHE is less efficient than ECDH; it requires more crypto
