To use a symmetric encryption scheme, the sender and receiver must securely share a key in advance. [12] Because symmetric key algorithms are nearly always much less computationally intensive, it is common to exchange a key using a key-exchange algorithm and transmit data using that key and a symmetric key algorithm.

Nov 01, 2016 The Definitive Guide to Encryption Key Management Fundamentals Encryption key management is administering the full lifecycle of cryptographic keys. This includes: generating, using, storing, archiving, and deleting of keys. Protection of the encryption keys includes limiting access to the keys physically, logically, and through user/role access.

Key exchange using public key cryptography, and key exchange using the Diffie-Hellman. You can take a look at this paper and it kind of will give you a look ahead into what's coming and how to make these key exchange protocols secure against man in the middle and not just secure against eavesdropping.

Symmetric and Asymmetric Encryption - Overview. In cryptography two major types of encryption schemes are widely used: symmetric encryption (where a single secret key is used to encrypt and decrypt data) and asymmetric encryption (where a public key cryptosystem is used and encryption and decryption is done using a pair of public and corresponding private key). algorithm - XOR Encryption, Decryption, and Cracking in Stack Exchange network consists of 177 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, --decrypt Enable decryption mode --key Specify the encryption key --guess Attempt to guess the encryption key by statistical analysis --single-byte Enable single-byte XOR mode (Default) --multi Public key cryptography - Diffie-Hellman Key Exchange
