Encrypt &; Decript A Stream
Hello
In my application, I want to encrypt a stream with password. But the gzip did not have a password method.
So is it someone tell me how encrypt with a key or something else, like RAS, DES, MD5...?
I have really no idea about this, so please offer me a simple way to do this (a demo will be better).
Thanks in advance!
...
OutputStream os = file_conn.openOutputStream ();
Gzip GZIPOutputStream = new GZIPOutputStream (os, 1);
gzip. Write (buffer);
...
InputStream is = file.openInputStream ((InputStream));
Gzip GZIPInputStream = new GZIPInputStream (is);
gzip. Read (target)
Most of the people when "Encrypting" a password don't encrypt using a common encryption process, they use a one-way process such as MD5 and don't remember the password in MD5 format. All platforms implement the same MD5 digest and then the password is passed around this more secure form.
If you get a password or try to use a password to secure data?
That said, I think you will find that it is not possible to write an encryption process that works on a stream. So I think that you have to change this procedure to read the data into a buffer encryption here.
Look for the javadoc for something like AESEncryptorEngine, you will find some links to examples that should help you to use.
One last thing, for a file gzip, gzip compresses the data, so you encrypt the first 16 bytes (header) you perform archive gzip practically useless, so if you are concerned about performance, then encrypt only the first 16 bytes. However if the gzip process does not have the compressed data (as it happens) it will be in the clear, it must encrypt the entire file.

Issue of TripleDESEncryptorEngine
Greetings,
I am using the following
* Simulator of Smartphone blackBerry 2.11.0.90
* BlackBerry JDE 4.6.1.23
I'm looking to encrypt an xml string to send to my server. Only the first 8 bytes of the output of. encrypt() contain data. I expect the output to more than 300 bytes long. Here's the code.
private static byte[] encrypt(String xml) throws MyException { try { byte[] output = null; int currentLen = xml.length(); String s1 = "\0\0\0\0\0\0\0\0"; // make sure the input to the cipher has a length divisible by the block size if (currentLen % 8 > 0) { String padding = new String(s1.getBytes(), 0, 8 - (currentLen % 8)); xml += padding; } // encrypt the XML stream using 3DES // blackberry TripleDESKey key = new TripleDESKey( Key.getBytes() ); TripleDESEncryptorEngine encryptionEngine = new TripleDESEncryptorEngine( key ); byte[] input = xml.getBytes(); output = new byte[input.length]; encryptionEngine.encrypt(input, 0, output, 0); return (output); } catch (Throwable e) { throw new MyException(e.getMessage()); } }
Any suggestions?

Hi all
I am aware that PGP Protocol is used to authenticate the source for the file and e-mail. It also lets you encrypt the telnet session?
All available CEC?
Matteo
Matteo,
PGP to encrypt files and e-mail - is not for encryption of network streams.
If you want to encrypt the telnet - well - just use ssh instead of telnet sessions where possible.
See you soon,.

Encrypted HLS streaming is supported in JavaFX 2.2?
Hi all
Thanks in advance for your answer. I have a JavaFX MediaPlayer can play the regular flow of HLS (sample of as Wowza stream VOD HLS) without any problem. However, when trying to access a stream encrypted from the same server, MediaViewer HLS throws an error 'Error invalid media'. The exact URL for the encrypted stream opens to other external actors, such as VLC. This makes me wonder if streams encrypted HLS is all supported by JavaFX Media Player. I can't find many references to it on these forums or Google either.
Please can someone confirm if encrypted HLS streaming is supported by JavaFX?
Thank you

Continually falling on Streaming music to ATV4
I have an ATV4 in visibility to the router and the iMac, and it's the only product on three continually give up when streaming music iTunes! The others are an Airport Express and ATV3 (who is in a room miles away!). In fact, it gets worse. It is irregular, sometimes settling when I bought it, but now it does not keep the connection for more than 5 minutes at a time. Yes, I tried all the resets, reboots, divide networks etc. This is the second ATV4 I had the first one had defective bluetooth. Any suggestions? Thank you
Have you tried to set the router to WPA2 - AES (CCMP) only encryption? ATV 4 seem to handle AES/TKIP mixed wrong.

followed the instructions of Mozilla to disable encryption WARNING guests but they keep appearing
Encryption warning boxes keep appearing despite having followed the instructions of Mozilla on how to disable these guests! Can anyone help please.
This particular security warning dialogue cannot be disabled - see the image I downloaded. But you can "continue" by clicking on the Enter key on the keyboard, instead of clicking on the button 'Continue' in this dialog box, so you don't have to use the mouse and take by the hand of the keyboard.
If you're wondering why Mozilla displays this message and does not provide a method to turn it off, do a search for "Firesheep" and "Blacksheep". Users on wireless connections are particularly likely to see their interceptions when the stream of data is not encrypted. There is a false sense of security by a Web site with an encrypted connection to connect to a Web site, but the cookie (which keeps this connection information) the Games Web site is "out in the open" when the connection goes to unencrypted when you leave this login page. This cookie can be used to steal your identity and allows the user to access your account.

The encryption does not work on MOTO G 2nd Gen
I tried to set up my email to work on my device and requires encryption to synchronize with a Microsoft exchange server. I launched the encryption, and he added a password as part of the process. When it's finished, he turned back and made me a password to decrypt the storage. I put the password that I created earlier in the process of encryption and it flashes the Android logo just turns off and then never light up again. I waited for an hour and then turned on manually and got the same decription password prompt. What the hell is happening?
Some have said that a password may have already been created if it has been previously owned or stolen. This is not the case, since it is a new phone that I bought at Staples.
Help, please! How can I solve this problem? I can't access my phone at all. So frustrating!
I had problems before initial encryption as well - the solution I found was to remove Exchange, reboot. Then activate encryption, then add Exchange.
If you can't get to everyone in your phone, you may need to perform a hard reset:
