对称密码算法(Symmetric-key Algorithm) 对称算法 是指加密秘钥和解密秘钥相同的密码算法,又称为 秘密秘钥算法 或 单密钥算法 。 该算法又分为 分组密码算法(Block cipher) 和 流密码算法(Stream cipher) 。 分组密码算法 又称块加密算法 加密步骤一:将明文拆分为 N 个固定长度的明文块 加密步骤二:用相同的秘钥...

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 restrictions, anyone can Free to use. In contrast, although AES is also a...

Asymmetric encryption is used for Bitcoin and other cryptocurrencies when consumers provide public keys that everyone will use and private keys that will be kept secret. To ensure that only funds belonging to legitimate owners can be spent, Bitcoin employs a cryptographic algorithm. ...

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...

That is, a single key known as secret key is shared between the sender and the receiver. Compared with asymmetric cryptography, symmetric cryptography is faster because of a single secret key and simplicity in its algorithm. However, symmetric cryptography has severe problems like, it does not ...
