self encrypting drive

one of the two is used to encrypt the data, the other one can be used to decrypt it. In addition, the private key cannot be inferred from the public key, and only the private key is used to decrypt the data encrypted with the public key. When sending an asynchronous encrypted message, The sender uses the receiver's public key to encrypt the message, making sure that only the receiver can use his private key to decrypt the text. If you do it in a different way, anyone can use the available publi

Created by Ken Stevens. Last edited by Steve Shaw, 1 ago. For your project we needed to encrypt a number of columns in the database for security purposes and tried out a tool called Jasypt and were able to meet we encryption requirements in under a day. Here is the changes we made to get it to work. Increase size of columns to being is encrypted in database. (3x was wasn't large enough, 10x was large enough). Change the type of non-varchar columns to varchar. Add the following dependency to your

Tips for encrypting Linux Command-line textI learned this method when I was learning Shell raiders, and it was simple and interesting, so I'm going to put it together and share it with you.ROT13 Text Encoding IntroductionROT13 (Rotary 13-bit, rotateby13places, sometimes a minus sign in the middle is called ROT-13) is a simple replacement cipher. It is generous to call ROT13 "Encryption", and "text obfuscation" is more accurate. Sometimes it is used to

Original: Encrypting a backup of a SQL Server databaseWell, recently in the study of database backup related things, considering that should be a database backup to add a secret, ready to search from the Internet to see what a good way, did not think it was quite chaotic ... First of all, I found from the Internet, the database backup encryption methods, there are three main types: 1. when using the BACKUP statement, add the PASSWORD parameter "This

Some friends asked why the optical drive will be stuck on the disc. In fact, it is not due to the poor quality of the disc or the aging of the optical drive laser head. When the optical drive is reading some unclear areas of the optical drive, you need to repeat it to adjust the position and power of the optical

Today we animate the methods and techniques for encrypting presentations in PowerPoint presentations. If you don't want someone to open your PowerPoint presentation, you can restrict it by setting an open password. Execute the Tools Options command, open the Options dialog box, switch to the Security tab, set a "password to open", press the "OK" button, in the subsequent pop-up dialog box, repeat the password, make sure to return, and then save the

GnuPG software package (Gnu privacy Guard,gnu privacy bodyguard), the name of the package is GPG. GPG uses the public key encryption method when encrypting files. 1. The first step is to create a key that will be used to send encrypted data and decrypt data in the future. If we execute the GPG comm
