How to decrypt using openssl encrypted string.
For example
, the key is 4937b554ddfb7d96b760220beefc440a
blowfish-cbc string - SPU/Vj4PNfhUqt+bXjUswA==
I do this:

export blowfishpass="4937b554ddfb7d96b760220beefc440a"
echo "SPU/Vj4PNfhUqt+bXjUswA==" | openssl bf-cbc -d -pass env:blowfishpass

I get a
bad magic number

Answer 1

"SPU/Vj4PNfhUqt+bXjUswA==" - base64 encoded data, at least there is a problem here. You are working in CBC mode but have not specified an IV anywhere. This is the second problem.
