GPG is a free encryption and digital signature software. It comes with Linux and can encrypt files and emails to ensure file integrity and security.GPG is divided into private key and public key. The public key can be used to disclose the files encrypted by the private key. The files encrypted by the Public Key can als

decrypted data: This is like magic. data becomes messy and can be recovered. This algorithm can also process file data. I wrote this small software: one is before file encryption, and the other is after encryption. The software is easy to write. The maximum file size that can be processed depends on the maximum memory size that your computer can apply for at a time. By the way, it may be a weak encryption method that can be easily cracked.

Use Gnupg to encrypt files in LinuxGuideGnuPG (GNU Privacy Guard or GPG) is an open source code for encryption or signature released with the GNU General Public License, which can be used to replace PGP. Most gpg software only supports the command line method, which is hard to grasp. Because gpg software is open source code, it is difficult to hide backdoors, so it is safer than pgp and other commercial sof

you do not use the pass option, the system will prompt you to enter the password by default and confirm that it requires manual operation) 4. OpenSSL functions are far more than that. If you are interested, refer to the OpenSSL manual. In Linux, you can use man OpenSSL to quickly obtain help files. For example, the file file.tar.gz is encrypted with a password of 123456.OpenSSL des3-salt-K 123456-In file.tar.gz-out file.tar.gz. des3 Decrypt file.t

Transferred from: http://netsecurity.51cto.com/art/201301/378513.htm1. IntroductionOpenSSL is a powerful cryptographic toolkit. Many of us already use OpenSSL to create RSA private keys or certificate signing requests (CSRs). But have you ever known that you can use OpenSSL to test your computer's speed? Or can you use it to encrypt a file or a message? This article will show you a few easy-to-learn tips on how to

Use WinRAR in C # to encrypt and compress files This example mainly implements: 1. compress the folder and its files 2. compress files in a folder 3. the compressed folder and its files are rar or zip 4. Extract 5. Encrypted compression and unencrypted Compression ----------

, which is consistent with the original SWF. The reason is that 256 is changed to 0, and your displacement is + 0. Of course it is not changed. Because there can be only 256 types of encrypted files generated by this encryption method, so I need to solve the problem from 0 ~ You can obtain the decrypted SWF by one of the 255. Therefore, we can improve the encryption algorithm by using strings as ciphertext. Convert the string into an ASCII array (for

For some private files, such as accounts and passwords, it is easy to forget if you do not need to write them down. However, you always feel a little uneasy when writing them down with common files, what if my computer is lost one day? Emacs supports file encryption.
