For cryptographically strong pseudo-random bytes you might use the pyOpenSSL wrapper around OpenSSL.

It provides the bytes function to gather a pseudo-random sequences of bytes.

from OpenSSL import rand

b = rand.bytes(n)

For cryptographically strong pseudo-random bytes you might use the pyOpenSSL wrapper around OpenSSL.

It provides the bytes function to gather a pseudo-random sequences of bytes.

from OpenSSL import rand

b = rand.bytes(7)

_{BTW, 12 uppercase letters is a little bit more that 56 bits of entropy. You will only to have to read 7 bytes.}

For cryptographically strong pseudo-random bytes you might use the pyOpenSSL wrapper around OpenSSL.

It provides the bytes function to gather a pseudo-random sequences of bytes.

_{BTW, 12 uppercase letters is a little bit more that 8 bits of entropy. You will only to have to read one byte.}
