QUESTION
I have a file that has been encrypted on Android using this code:
...ANSWER
Answered 2020-Nov-12 at 09:51Okay, I think I figured the problem. Obviously, there is a problem with NSData.bytes and one should work withUnsafeBytes. Furthermore, my issue may was that the IV was not part of the data, as many examples assumed, so I missed 16 bytes when decrypting. The following code works for me, hope it will help someone!

i have got a private key in xml format from m team. I want to decrypt messages(in app) that they send me.

I decided to take only module and D from code as i ve read it s enough to decode When i run this code i have an error: java.lang.ArrayIndexOutOfBoundsException: too much data for RSA block

I want to replace white-spaces in dbyte with '#' character, and db should be passed to the procedure by stack.
I've written next snippet and replacing is working, but I can't understand how to pass db to procedure func properly.

QUESTION
I'm trying to generate a CombGuid with my own seed, and I need that code be generated equals both in C# and SQL Server.
I'm following the idea of CombGuid generation as stated in this site: http://www.informit.com/articles/article.aspx?p=25862&seqNum=7
I'm also borrowing C# code from: https://github.com/richardtallent/RT.Comb
The problem I can't make the last group of the Guids be generated equal in both languages. In SQL Server I know it's working, because I can reverse the Guid to Bigint again.
But in C#, when I try reverse it, the value is returned lower than the original.
What am I doing wrong?
Here is the code:
C#:
...ANSWER
Answered 2018-Feb-22 at 06:13Problem is Math.Floor return type is double in your case, so type of ms is double. Floating point numbers are represented differently in memory, so BitConverter.GetBytes(double) produces not the same result as BitConverter.GetBytes(long), even if values are the same. So to fix, cast the result to long, just as you do in your SQL query (with as bigint):
QUESTION
I need to encrypt an audio file while it is being generated. I am encrypting header with dummy data(because I don't know the actual size of audio data) at the starting and encrypting the audio data on the fly. My plan is to update the header at the end with actual data size of audio file.
But, When I tried to overwrite the encrypted header data with newly encrypted header data of same size by using same key and IV and try to decrypt later, I am getting junk data generated.
Why is this happening even though I am using same key and IV? In the below code I tried to simulate what I am doing. Encrypted file of size 64 bytes generated and decrypted file of size 50 bytes generated.
Without updation: abcdabcdab0123456789012345678901234567890123456789
With header updation: ABCDABCDAB÷‹þ@óMCKLZƒÖ^Ô234567890123456789
Expected output: ABCDABCDAB0123456789012345678901234567890123456789
Is this the right approach to achieve partial update of already encrypted data?
...ANSWER
Answered 2017-Nov-28 at 09:56I suggest you update several things:
you are opening multiple outputstreams to the SAME file, which is very strange, the runtime should not allow you to do that. So - write only with a single output if you want any predictable results.
You may read about the mode of operations see the CRT mode uses no padding and allows you to update only a portion of the ciphertext (assuming you use no authenticated encryption). So
AES/CTR/NoPaddingcould solve your problem. (and there should be no extra bytes if you do it correctly)you can update a portion of the file using the RandomAccessFile and overwrite portion of the ciphertext what is needed.
QUESTION
I'm new in objective-C and I'm not getting to converting an audio file to char exactly I need. It is ignoring a sequence of zeros (0) and it's deforming the data structure.
My code is so:
ANSWER
Answered 2017-Mar-07 at 13:08If I understand your problem correctly the issue is with your format %x - this produces a hexadecimal text representation with sufficient digits to represent the value and without any leading zeroes.
For example the value 32 will produce the text 20, while the value 12 produces c - only one character long.
If you wish to convert to hex representation and then back again each of your byte values needs to produce the same number of characters - as otherwise you can't know where the boundaries are between each byte's representation.
To do this you can use the format %02x, which means always produce two characters padding with zeroes as required. For example with this format 12 will produce 0c.

Install DByte
Or you can just download the file and then include it in your scripts.
To begin using the DB object you need to assign a PDO connection object. If you are using SQLite or PostgreSQL instead of MySQL you will need to change the quoted identifier to the correct character (instead of the MySQL tilde `). If you are using PostgreSQL you will also need to set the PostgreSQL marker.
