QUESTION
I am rewriting some code writed in Wolfram Mathematica to Python. And, in some moment I needed an analogue of function ArrayResample[array,dspec]
. May be you know a function from any package (NumPy or SciPy)?
ANSWER
Answered 2019-Jan-06 at 14:48You could use scipy.ndimage.map_coordinates
.
Here are map_coordinate
equivalents of the ArrayResample examples:
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/NoPadding
could 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.
