the Advanced encryption algorithm, truly achieves the ultra high encryption intensity, lets your encrypted file and the encrypted folder airtight, and the speed also express, each second can encrypt the 25-50m data.
There are two ways to encrypt data:
Method 1: In the Software window of the file browsing control Select to encrypt the file or encrypted folder, and then click the "Data Encryption" button, enter the encryption password Click "OK" can be.
Tip: To keep in mind the password you se
Today, in the Linux editing file/etc/rc.local, you should enter after editing: X saved, the result accidentally entered: X (uppercase X), and then prompted two times to enter the password, I followed the prompts to operate successfully.
Because it was the first time I ran into it, I didn't know it was a file encryption.
Later restart the machine, found oracle10g database and did not boot from the start, and then go to see rc.local, found with more command to see is garbled, with VI input correct
PHP uses XOR (XOR) to encrypt/decrypt files
Principle: Each byte of the file with the key for the bitwise XOR or operation (XOR), decryption and then perform an exclusive OR operation.
The code is as follows:
01.02.$source = ' test.jpg ';$encrypt _file = ' test_enc.jpg ';$decrypt _file = ' test_dec.jpg ';$key = ' d89475d32ea8bbe933dbd299599eea3e ';07.08.echo
, decrypt the files encrypted with VI (provided that you know the encrypted password):1) Use VI to open the file, such as Text.txt, to enter the correct password, and then when editing, set the password to empty, by entering the following command:: Set key=Then directly enter, after saving the file, the file has been decrypted.2) or This is OK:After opening the file correctly with ": X" instruction, and the
In the development of some PHP files need to be modified, in part through Zend encryption, Notepad opened after the following: You need to use Dezender to decrypt the download link as follows:dezender.7zAfter downloading to the C drive (not the path with Chinese), such as extracting to another location, please open the Dezender\php5\php5\php.ini file, to the end of the file; Local Variables: ; Tab-width:4
-IV option: Enter the initial variable. (If this option is not used, Openssl uses a password to automatically extract the initial variable ).
-Salt option: whether to use the salt value. It is used by default.
-P option: print the encryption key used by the encryption algorithm.
1. Use the aes-128-cbc algorithm to encrypt files:
Openssl enc-aes-128-cbc-in install. log-out enc. log
(Note: Here install. log is the file you want to en
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
