Key Generation
When used with asymmetric ciphers for key transfer, pseudorandom key generators are nearly always used to generate the symmetric cipher session keys. However, lack of randomness in those generators or in their initialization vectors is disastrous and has led to cryptanalytic breaks in the past. Therefore, it is essential that an implementation uses a source of high entropy for its initialization.

Famous quotes containing the words key and/or generation:
“This is the Key of the Kingdom:
In that Kingdom is a city;”
—Unknown. This Is the Key (l. 1–2)
“Through centuries he lived in poverty.
God only was his only elegance.
Then generation by generation he grew
Stronger and freer, a little better off.
He lived each life because, if it was bad,
He said a good life would be possible.”
—Wallace Stevens (1879–1955)
