How can you store a rsa key pair in a django model / sqlite db -

-

i using pycrypto within django (python 2.7, django 1.5m sqlite), create field store rsakey object. how can this? converting string , seems pretty error prone , since random bytes in there, not trust approach. able store random keys in charfield base-64 encoding (like this: random.new().read(16).encode('base64')). keypair? saw in current dev version of django, binary field incorporated, need stick 1.5.

any appreciated.

thanks gerd

you need store private key, because can generate public key private one.

>>> crypto.publickey import rsa >>> rsakey = rsa.generate(1024)

the public key can exported with

>>> rsakey.publickey().exportkey()

to save private key might want convert text exportkey() method , store in django-textfield:

>>> rsakey.exportkey() '-----begin rsa private key-----\nmi...-----end'

converting text rsa key object easy too:

>>> rsa.importkey('-----begin rsa private key--- ....')

gets rsaobj 1 generated @ first.

you might try "hard way" creating own model field class, if intend use functionality in other areas well. see https://docs.djangoproject.com/en/1.5/howto/custom-model-fields/

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2...
