MD5: Why am I getting different results for the same string? Question: I expected the following code to return the same result in each case since the string values are the same but instead got a different result each time. What can I do (if anything) to address this? import hashlib a = ‘some text’ …
How to find a collision of first 56 bits for MD5(MD5(x)) for input data with the same prefix? Question: I have a code to find the collision of the first 56 bits of the hash function: md5(md5(x)) (using the Floyd algorithm to find cycles). The script returns two strings (hare, tortoise) for which a collision …
How do I know if the 'usedforsecurity' flag is supported by hashlib.md5? Question: When I run the following on my Macbook, I get the error: >>> import hashlib >>> hashlib.md5(usedforsecurity=False) Traceback (most recent call last): File “<stdin>”, line 1, in <module> TypeError: openssl_md5() takes no keyword arguments But when I run it on my Linux …

Generating one MD5/SHA1 checksum of multiple files in Python Question: I have looked through several topics about calculating checksums of files in Python but none of them answered the question about one sum from multiple files. I have several files in sub directories and would like to determine if there was any change in one …
How do I calculate the MD5 checksum of a file in Python? Question: I have written some code in Python that checks for an MD5 hash in a file and makes sure the hash matches that of the original. Here is what I have developed: # Defines filename filename = "file.exe" # Gets MD5 from …
Is it ok to remove the equal signs from a base64 string? Question: I have a string that I’m encoding into base64 to conserve space. Is it a big deal if I remove the equal sign at the end? Would this significantly decrease entropy? What can I do to ensure the length of the resulting …
Computing an md5 hash of a data structure Question: I want to compute an md5 hash not of a string, but of an entire data structure. I understand the mechanics of a way to do this (dispatch on the type of the value, canonicalize dictionary key order and other randomness, recurse into sub-values, etc). But …
How to get MD5 sum of a string using python? Question: In the Flickr API docs, you need to find the MD5 sum of a string to generate the [api_sig] value. How does one go about generating an MD5 sum from a string? Flickr’s example: string: 000005fab4534d05api_key9a0554259914a86fb9e7eb014e4e5d52permswrite MD5 sum: a02506b31c1cd46c2e0b6380fb94eb3d Asked By: super9 || Source …
Generating an MD5 checksum of a file Question: Is there any simple way of generating (and checking) MD5 checksums of a list of files in Python? (I have a small program I’m working on, and I’d like to confirm the checksums of the files). Asked By: Alexander || Source Answers: There is a way that’s …
