Yes.

In hex, those values are 63, 05, and 69. They're in both files, a few 
bytes just before the three names.

Yes - as above.

If, for example, your data had the salaries of three folks (one being 
myself, Jill), and I knew my salary was 12345 (that's 39 30 in hex, 
reverse order), I could then easily extract the salaries of the other 
two entries.

Probably OK if the data is not super-sensitive.

If the data is very sensitive, such as passwords, then maybe all file 
copies should be encrypted. And, if any data is S-U-P-E-R sensitive, 
then all memory copies should probably remain encrypted, except for the 
moments the actual decrypted values are used.
