Jce.jar Security/us_export_policy.jar Security/local_policy.jar Ext/sunjce_provider.jar These packages are loaded automatically by the Java runtime, so applications with the main function do not need to be set to the CLASSPATH environment variable. For Web applications, you do not need to add these packages to the Web-inf/lib directory. The following is a sample code for the 3DES encryption decryption algor

I am also a novice php, through W3cschool to understand the basic principles of PHP after the write. But still rookie.First, regardless of 3DES encryption method is right, methods are online, in the run time reported a mistake, the younger brother died.

Today, the 3DES encryption method to do a deep understanding, because the recent project needs, to encrypt the interface, so the unanimous discussion, the use of DES encryption, but there are some problems, wasted some time, here, the author will own DES encryption method to share to everyone, Hope to help everyone ~ ~

I need to talk to you right now. NET, data is encrypted, but now the problem is, I use PHP encryption after processing and after the. NET encryption processing data is not equal, their code there is no problem, this can be confirmed, then my side of the encryption there is a problem, and now the specific problem is not very clear, please the great God, the follow

I need to contact you here. NET to perform data interaction, the data needs to be encrypted, but now the problem is that after I use PHP to encrypt and. the data after the net encryption is not equal, and the Code on their side is correct. This can be confirmed, so the encryption on my side... I need to contact you here. NET to perform data interaction, the data needs to be encrypted, but now the problem is

3DES (or Triple DES) is the generic term for a triple-Data encryption Algorithm (Tdea,triple-Encryption-algorithm) block cipher. It is equivalent to applying three DES encryption algorithms to each block of data. The encryption key length of the original des Cipher becomes e
