core_id = raw.split('+')[1] # "mst2euvwzrp0472t" The string i+mst2euvwzrp0472t+fixed is not random noise — it follows a plausible pattern: a short prefix, a fixed-length alphanumeric core, and a status suffix separated by plus signs. The “fix” depends on context: remove metadata, decode URL encoding, or split fields.
Original (padded): mst2euvwzrp0472t== Decoded (hex): 9b 2b 76 e9 5f 6c f4 7b 8d f1 d2 f7 That yields binary data, not readable text. So not a direct base64 of an English phrase. URL-decode i+mst2euvwzrp0472t+fixed → i mst2euvwzrp0472t fixed (spaces). That is more readable: three parts: i , mst2euvwzrp0472t , fixed . The middle part mst2euvwzrp0472t could be a random-looking ID, and fixed might be a status. i+mst2euvwzrp0472t+fixed
Or if you need to extract the core ID:
int("mst2euvwzrp0472t", 36) Output would be enormous — possibly a UNIX timestamp in nanoseconds. The presence of +fixed strongly suggests a manual annotation. In issue tracking systems, a key might be marked +fixed to indicate the associated bug or task has been resolved. Alternatively, in a data pipeline, a record might be flagged as “fixed” after cleansing. core_id = raw
Try decoding just the core part: mst2euvwzrp0472t (15 chars). Base64 of length 15 is invalid without padding. Padding with = gives 16 chars, divisible by 4. Let’s test conceptual decoding (pseudo): So not a direct base64 of an English phrase
