Look at script/entry point.sh - you’ll see that a Python command is being run and exported as an environment variable to create the Fernet key; Copy the Python code and package it into an export statement with the env variable name FERNET_KEY
If the message preparer is able to find cryptographic hash function collisions (i.e., two messages producing the same hash value), then they might prepare meaningful versions of the message that would produce the same hash value and digital signature, but with different results (e.g., transferring $1,000,000 to an account, rather than $10).
I am trying to decode Base64 into Hex for about 200 Base64 data and I am getting this following error. It does decoding for 60 of them then stops. Base64 strings, properly padded, have a length that is a multiple of 4, so you can easily re-add the padding

Dino Viehland Well, CPython at least still enforces the padding, even if it's ignoring the invalid characters. Here's Seo's repro 'simplified' to go straight to binascii (just to get to the root API): '' And then sending a valid character, invalid padding: Traceback (most recent call last): File "", line 1, in ? binascii.Error: Incorrect ...

Nov 27, 2017 · If there’s a padding error it probably means your string is corrupted; base64-encoded strings should have a multiple of four length. You can try adding the padding character ( = ) yourself to make the string a multiple of four, but it should already have that unless something is wrong
