Third, network transmission encryption Goldengate when transferring data, the default is unencrypted. Data can be encrypted before the goldengate is transmitted over the network and transmitted to the target side to decrypt the data before it is written to the trail file. This effectively protects the data during transmission. The steps for encrypting network transmission are as follows. Generate multiple keys on the production side and then save t

Digital signatures and data encryption are required to use the RSA and other asymmetric encryption algorithm Where the digital signature is the sender with the private key encryption, the receiver with the pub
Most of the login and registration modules of the responsible company have been implemented recently. The idea of realizing the password retrieval function is as follows: 1. the user forgets the password and needs to retrieve the password. 2. The background will send the Password Reset page to the user's mailbox through a series of encryption processing. 3. You can reset the password through an annoying link in your mailbox. The following code is used
When making some reports and company tables, we often need to encrypt Excel tables or set them as read-only properties to protect these important tables. Encrypting a table prevents others from opening the table, and only opens it correctly by typing the correct password. When set to read-only, you can prevent others from modifying the file, only reading the table, unless you enter the correct password to modify the contents of the table. Excel encryption

You should use the complete result obtained by crypt () as the salt value for password verification to avoid problems caused by different hash algorithms. (As described above, the password hash based on the standard DES algorithm uses a 2-character salt value, but the MD5 algorithm uses a 12-character salt value. Use the md5 () function to encrypt (use? RSA Data Security's MD5 packet algorithm calculates the MD5 hash value of str .), The security

Note: This change can only be used at the beginning of website construction. If you change it halfway, it will cause problems. You may be familiar with MD5, but are you sure you do? Do you know how the hash is implemented? Although we generally don't need to go to the root of the problem, we just need to download programs compiled by others directly. Most people know the algorithm, so there are a lot of tools on the Internet to crack the MD5 hash value, but we can use our imagination to fully m
