In modern Cryptography Plaintext is encrypted in its binary form. The process of the encryption can be either in bit stream or block stream in which in the bit stream, each bit is encrypted to its equivalent ciphertext and for a block stream the bit is clustered into group of bits.

Explain the key life cycle in key management for modern cryptography.
