2. ElGamal encryption - Wikipedia

   en.wikipedia.org/wiki/ElGamal_encryption

   The first party, Alice, generates a key pair as follows: Generate an efficient description of a cyclic group of order with generator. Let represent the identity element of . It is not necessary to come up with a group and generator for each new key.

3. ssh-keygen - Wikipedia

   en.wikipedia.org/wiki/Ssh-keygen

   Provides custom key comment (which will be appended at the end of the public key). -K Imports a private resident key from a FIDO2 device. -p Requests changing the passphrase of a private key file instead of creating a new private key. -t Specifies the type of key to create (e.g., rsa). -o Use the new OpenSSH format. -q quiets ssh-keygen.

4. Elliptic-curve Diffie–Hellman - Wikipedia

   en.wikipedia.org/wiki/Elliptic-curve_Diffie...

   Elliptic-curve Diffie–Hellman (ECDH) is a key agreement protocol that allows two parties, each having an elliptic-curve public–private key pair, to establish a shared secret over an insecure channel. [1] [2] [3] This shared secret may be directly used as a key, or to derive another key.

5. Key generation - Wikipedia

   en.wikipedia.org/wiki/Key_generation

   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 encrypts data with the receiver's public key; only the holder of the private key can ...

6. Public-key cryptography - Wikipedia

   en.wikipedia.org/wiki/Public-key_cryptography

   Public-key cryptography, or asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys. Each key pair consists of a public key and a corresponding private key. [1] [2] Key pairs are generated with cryptographic algorithms based on mathematical problems termed one-way functions.

7. Elliptic-curve cryptography - Wikipedia

   en.wikipedia.org/wiki/Elliptic-curve_cryptography

   Elliptic-curve cryptography (ECC) is an approach to public-key cryptography based on the algebraic structure of elliptic curves over finite fields.ECC allows smaller keys to provide equivalent security, compared to cryptosystems based on modular exponentiation in Galois fields, such as the RSA cryptosystem and ElGamal cryptosystem.

8. RSA (cryptosystem) - Wikipedia

   en.wikipedia.org/wiki/RSA_(cryptosystem)

   RSA (Rivest–Shamir–Adleman) is a public-key cryptosystem, one of the oldest widely used for secure data transmission.The initialism "RSA" comes from the surnames of Ron Rivest, Adi Shamir and Leonard Adleman, who publicly described the algorithm in 1977.

9. Key management - Wikipedia

   en.wikipedia.org/wiki/Key_management

   A key management system (KMS), also known as a cryptographic key management system (CKMS) or enterprise key management system (EKMS), is an integrated approach for generating, distributing and managing cryptographic keys for devices and applications. They may cover all aspects of security - from the secure generation of keys over the secure ...
