Cryptography series: blowfish symmetric key grouping algorithm Introduction Blowfish is a symmetric key block encryption algorithm invented by Bruce Schneier in 1993. Similar DES and AES are block encryption algorithms. Blowfish is used to replace the DES algorithm, and Blowfish has no commercial restric...

A commonly used algorithm today for symmetric cryptography is AES, which means "Advanced Encryption Standard". 1 AES (Symmetric crypto) This algorithm has a combination of substitutions and transpositions using a key of fixed length. A key of fixed length means that the algorithm can only have ...
You can use the CREATE SYMMETRIC KEY statement to create the encryption key: CREATE SYMMETRIC KEY KEYNAME [AUTHORIZATION OWNERNAME] WITH [KEY_SOURCE = ‘PASS_PHRASE’ | ALGORITHM = < ALGORITHM > | IDENTITY_VALUE = ‘IDENTITY_PHRASE ‘] ENCRYPTION BY [CERTIFICATE CERTIFICATE_NAME | PASSWORD...
Without doubt, AES (Advanced Encryption Standard) and Keccak/SHA-3 (Secure Hash Algorithm 3) are the two most used and famous symmetric cryptography algorithms. Winners of the standardization processes sponsored by the U.S. National Institute of Standards and Technology (NIST), they are currently...

Symmetric encryption uses a single key for message encryption and decryption. Nevertheless, the sender uses the public encryption key and the private decryption key in asymmetric encryption. In contrast to the symmetric coding algorithm, the execution of asymmetric algorithms is slower. That is due to...
