RSA is the first perfect Public Key algorithm. It can be used for both encryption and digital signature. RSA is named by the first letter of its three inventors Ron Rivest, Adi Shamir, and Leonard Adleman. This algorithm has withstood years of in-depth password analysis, although cryptographic analysts cannot prove or

Signed, checked, asymmetric, and decrypted via OpenSSL need to be used in conjunction with X.509 certificates (such as CRT and PEM) files. For a variety of reasons, this class is not very perfect, welcome to various tests. _getpublickey ($p

This is a creation in Article, where the information may have evolved or changed. Security is always important, and every language is implemented for general-purpose cryptographic algorithms. A while ago, with go implementation of RSA and DES Encryption and decryption, in this share. (for RSA and DES encryption algorithms themselves, please refer to the relevant information) In PHP, many functions are often

Both the rsacryptoserviceprovider and dsacryptoserviceprovider constructors can specify a cspparameters struct. Using this cspparameters struct, We can customize the CSP local storage name (that is, the key container: keycontainer) of the asymmetric encryption algorithm. This container is saved in the Windows user configuration file by default. If you want to store the key within the computer range (rather than the user range), you can use the usemach

(byencrypted, false);String strdecryptedpwd = Utf8encoder. GetString (bydecrypted);Console.WriteLine ("Decrypted Password is: {0}", strdecryptedpwd);}You can clearly see that the password is encrypted to 128-byte length of the ciphertext, why is fixed 128 bytes it? This is because our RSACryptoServiceProvider default generated key length is 1024, that is, 1024-bit encryption, so no matter how long the password you want to encrypt, it will generate a cipher length is 128 bytes, also because of t

RSA is a two-way encryption algorithm, which is the first algorithm that can be used for both data encryption and digital signature. It is easy to understand and operate, and very popular. The name of the algorithm is named after the inventor: Ron Rivest, Adi Shamir and Leonard Adleman. However, the security of
