to define how the extents are managed when you create a temporary table space. Modifying a temporary table space Modifying a temporary tablespace mainly has the following actions: Add temporary files To modify the size of a temporary file Modify the status of a temporary file Add temporary files Alter tablespace temp0304 Add ' F:\SQL\tempfile0306.dbf ' size 10m; Modify temporary file size Alter Database tempfile ' F:\SQL\tempfile0306.dbf ' resize 20m; You can also mo

RSA Tool class. Provides encryption, decryption, and generation of key equivalence methods.RSA Encryption Principle Overview:The security of RSA relies on the decomposition of large numbers, and the public and private keys are functions of two large primes (decimal bits greater than 100).It is assumed that the difficulty of inferring clear text from a key and cipher is equivalent to decomposing the product

(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

In our practical use, encryption is an important means to ensure data security. In the past, MD5 and SHA1 algorithms were used for data encryption when ASP was used. Although these two algorithms are fast and effective, they cannot be used to reverse the ciphertext encrypted by them, that is, decryption. Therefore, these two methods are not suitable for data decryption. Of course, you can also write suitable encryption and decryption programs by yourself. However, this requires a high level of m

OpenSSL RSA is the processing tool for RSA keysThe OpenSSL Pkey is a general-purpose asymmetric key processing tool that is basically consistent in usage, so it only illustrates OpenSSL RSA.They are very simple to use, basically the input and output of the private key or the role of the public key .OpenSSL RSA [-in filename] [-passin arg] [-passout arg] [-out fil

EncryptionAlgorithmRSA Algorithm It is the first algorithm that can be used for both data encryption and digital signature. It is easy to understand and operate, and is also popular. The algorithm is named by the inventor Ron Rivest, Adi Shamir, and Leonard Adleman. However, the security of RSA has never been proved theoretically. It has experienced various attacks and has not been completely cracked yet. I. R
