Key generation is the process of generating keys in cryptography. A key is used to encrypt and decrypt whatever data is being encrypted/decrypted. A device or program used to generate keys is called a key generator or keygen. Cryptography Stack Exchange is a question and answer site for software developers, mathematicians and others interested in cryptography. Where do key generation algorithms take the randomness from? Ask Question Asked 2 years, 11 months ago. Applications that generate key get the randomness.
Key generation is the process of generating keys for cryptography. The key is used to encrypt and decrypt data whatever the data is being encrypted or decrypted.
Modern cryptographic systems include symmetric-key algorithms (such as DES and AES) and public-key algorithms (such as RSA). Symmetric-key algorithms use a single shared key; keeping data secret requires keeping this key secret. Public-key algorithms use a public key and a private key. The public key is made available to anyone (often by means of a digital certificate). A sender will encrypt data with the public key; only the holder of the private key can decrypt this data.
Since public-key algorithms tend to be much slower than symmetric-key algorithms, modern systems such as TLS and its predecessor SSL as well as the SSH use a combination of the two in which:
- RC4 Algorithm. In the RC4 encryption algorithm, the key stream is completely independent of the plaintext used. An 8. 8 S-Box (S0 S255), where each of the entries is a permutation of the numbers 0 to 255, and the permutation is a function of the variable length key. There are two counters i, and j, both initialized to 0 used in the algorithm.
- Cryptographic key generation from voice Abstract: We propose a technique to reliably generate a cryptographic key from a user's voice while speaking a password. The key resists cryptanalysis even against an attacker who captures all system information related to generating or verifying the cryptographic key.

- One party receives the other's public key, and encrypts a small piece of data (either a symmetric key or some data that will be used to generate it).
- The remainder of the conversation (the remaining party) uses a (typically faster) symmetric-key algorithm for encryption.
The simplest method to read encrypted data is a brute force attack–simply attempting every number, up to the maximum length of the key. Therefore, it is important to use a sufficiently long key length; longer keys take exponentially longer time to attack, making a brute force attack invisible and impractical.
Currently, commonly used key lengths are:

- 128-bits for symmetric key algorithms.
- 1024-bits for public-key algorithms.

Key generation algorithms[change | change source]
In computer cryptography keys are integers. In some cases keys are randomly generated using a random number generator (RNG) or pseudorandom number generator (PRNG), the latter being a computeralgorithm that produces data which appears random under analysis. Some types the PRNGs algorithms utilize system entropy to generate a seed data, such seeds produce better results, since this makes the initial conditions of the PRNG much more difficult for an attacker to guess.

In other situations, the key is created using a passphrase and a key generation algorithm, using a cryptographic hash function such as SHA-1.

- Distributed key generation: For some protocols no party should be in the sole possession of the secret key. Rather, during distributed key generation every party obtains a share of the key. A threshold of the participating parties need to work together in order to achieve a cryptographic task, such as decrypting a message.
