Effects of changing Django's SECRET_KEY
...t key needs to be the same size as the output. The key also needs to be in bits. Each digit in base64 represents 6 bits. So if you had a 50 character password, you would have a 50 x 6 = 300 bit secret key. If you are using SHA256, then you would need a 256 bit key (sha256 uses 256 bits by definition...
Why do we use Base64?
...encodings were created (e.g. Baudot code) which used a different number of bits per character until eventually ASCII became a standard with 7 bits per character. However most computers store binary data in bytes consisting of 8 bits each so ASCII is unsuitable for tranferring this type of data. Some...
