yea, its a D in there ;-)

blowfish.decrypt('fCWBLoeH6/o=', '5KXNaH', {cipherMode: CBC, outputType: string});
output: "CÔ>‚vS‚"

I can't understand what i'm doing wrong. Please, when someone get this BTC to write here to all who want to learn - how he did that.

No idea wich library you use and wich parameter sequence you need. maybe the other way around?

I've tried 4 online decryption tools. All of them shows me different results.
Should the result be clear string without special chars?
And is this the plain text "fCWBLoeH6/o=" or it is the result?
