where can you find the old BitCoinJ version 0.1 and 0.2 and 0.3
This seems to be more of a question about how GitHub works than a question about Bitcoin itself. But maybe it’s related enough to Bitcoin to justify this.
The Github repository for Bitcoinj currently only has information on 14 Bitcoinj releases from v0.16.2 on April 5, 2023 to v0.17 on February 21, 2025.
But the list of commitments goes further back and the commit page referenced in the question starts with a commit July 20, 2011 titled “Updating repo URLs. Patch from Gary Rowe.”.
There is one on the right <> button with tooltip “Browse the repository at this point” If you click on it, you will come to a page with a green color <> Code ▼ knob. Has a dropdown from that button “Download Zip”.
If you click on that link I expect you will get the source code which can in principle be compiled using the appropriate Java Development Kit (JDK) to recreate Bitcoinj as it existed on Gary Rowe’s system on the date of that commit.
As others have noted. It is unlikely that an old version of BitcoinJ will provide any help in the practical use of a 32-character string of unknown origin and unknown meaning.
In particular, if you know which 21st century encryption algorithm was used, you cannot decrypt the encrypted data without some knowledge of the encryption key.
