Get MD5 Checksum for Very Large Files

I've written a script that reads through all files in a directory and returns md5 hash for each file. However, it renders nothing for a rather large file. I assume that the interpreter has some value set for maximum processing time, and since it takes too long to get this value, it just skips along to other files. Is there anyway to g...

Most memory-efficient way of holding base64 data in Python?

Suppose you have a MD5 hash encoded in base64. Then each character needs only 6 bits to store each character in the resultant 22-byte string (excluding the ending '=='). Thus, each base64 md5 hash can shrink down to 6*22 = 132 bits, which requires 25% less memory space compared to the original 8*22=176 bits string. Is there any Python...

There is a md5crypt routine on OS X, but unfortunately, i...
