Other types of encryption are also available. REBOL supports RSA public key encryption, DSA digital signature algorithm, and DH (Diffie Hellman) key exchange. These are covered in theREBOL Encryption Document. Encryption Padding The examples above use padding to allow the results of decryption to b...
For example, the Signature engine class provides access to the functionality of a digital signature algorithm. The actual implementation supplied in a SignatureSpi subclass (see next paragraph) would be that for a specific kind of signature algorithm, such as SHA256withDSA or SHA512withRSA. The...
How identity is verified is a complicated process but Digital Ocean has a very nice write-up of how it works. At a high level, identity is verified by the server encrypting a challenge message with the public key, then sending it to the client. If the client cannot decrypt the challenge...
Hash functions use a one-way encryption algorithm, known as a hash value, to encrypt plaintext into ciphertext. Once you convert plaintext to the hash, you cannot revert it to plaintext. For any given hash function, no two plaintexts will yield the same hash. Hashing algorithms help en...
DSA (Digital Signature Algorithm) Symmetric encryption is a type of encryption where only one key is used to encrypt and decrypt the information. In this situation, both sender and recipient share the same encryption key. Some examples of symmetric encryption algorithms include: AES (Advanced Encryp...

The generation of SSH keys can be through a public key cryptographic algorithm, the most common being RSA or DSA. At a very high-level SSH keys are created via a mathematical formula that uses 2 prime numbers and a random seed variable to output the public and private keys. This is a ...

Alternatively, you can also use theDSA (Digital Signing Algorithm)technology to create the public/private key. ssh-keygen-tdsa Note: there has been much debate about the security of DSA and RSA. In my opinion, unless you are very particular and love to delve into the technical detail between...
