Diffie–Hellman key exchange (D–H) is a specific method of securely exchanging cryptographic keys over a public channel and was one of the first public-key protocols as originally conceptualized by Ralph Merkle. D–H is one of the earliest practical examples of public key exchange implemented within the field of cryptography. Traditionally, secure encrypted communication between two parties required that they first exchange keys by some secure physical channel, such as paper key lists transported by a trusted courier. The Diffie–Hellman key exchange method allows two parties that have no prior knowledge of each other to jointly establish a shared secret key over an insecure channel. This key can then be used to encrypt subsequent communications using a symmetric key cipher.
Diffie–Hellman is used to secure a variety of Internet services. However, research published in October 2015 suggests that the parameters in use for many D-H Internet applications at that time are not strong enough to prevent compromise by very well-funded attackers, such as the security services of large governments.
The color hurts, It blinds my eyes.
With mystic words, They hypnotize
and you know it’s true.
Look up to the sunset,
and notice that I’m fine
it’s never understanding
and it’s a flaw of yours and mine
oh yeah,
I cannot speak, Can’t find words to say.
but I’m improving more everyday
and it’s all for you
Heavy is the head
of the man who wears the crown
Who’s been lost for oh so long
but now I’ve finally found a way.
What have they said, All hypocrisy
Their evil cuts so deep into me.
Because it’s so untrue.
Hand of god is overrated
Time’s not gone it’s devastated
Evil is more complicated
