...
Hello
world!
If I send it as ASCII (or UTF-8) it will look like this:
72 101 108 108 111 10 119 111 114 108 100 33
The byte 10 is corrupted in some systems so we can base 64 encode these bytes as a Base64 string:
SGVsbG8sCndvcmxkIQ==
Which when encoded using ASCII looks like this:

Thus Git has in effect already migrated to a new hash that isn't SHA-1
