Parameters:objectNumber - The data object number.genNumber - The data generation number.data - The data to encrypt.output - The output to write the encrypted data to.decrypt - true to decrypt the data,

it's important to note that the decoder class in the missing assembly does appear to be working fine since i'm able to encode and then decode again as i've previously mentioned. The application may be trying to use a different padding mode for decryption than the one used for encryption. So I went to the General tab on the server, changed the protocol to TCP and the port to 1999. This is the contents of the file that configured the syslog listener on the logstash box:Code: [Select]input {
tcp {
mode => "server"
port => "6514"

Unfortunately the code's too long to post here. Summary: This How To shows you how to create a managed class library to provide encryption functionality for applications. when I do a netstat -ln on the "server" box, I don't see a listener on the TCP port I configured, but I do see a stream listener pointing to the This is covered in detail in the KMS Developer Guide but I’ve also provided a summarized version below.

The following diagrams illustrate where encryption and decryption are performed for SSE and CSE. Since the ciphertext can legitimately contain any byte value you should instead use the stream's Length property to determine the length of the ciphertext. Well, then I'm too busy to look at your code any further. –James K Polk Oct 6 '13 at 14:41 Hi, I read your comment. Or invalid settings for decrypted data padding, so the method can't calculate the correct size of pure encrypted bytes without padding. –Kosmos May 19 '15 at 18:34 Have you

The encryption process uses the same key/IV pair that decryption uses, and since it will decrypt a portion of the stream I feel like that's working fine - it just ends Check out our Big Data and Streaming data educational pages.
