| Mode of operation: | |
| Each of the *.in files is XER-decoded, then converted into DER, | |
| then decoded back from DER, then encoded into XER again, | |
| and finally compared to the original encoding. | |
| Naming conventions: | |
| *-B.in - The file is intentionally (B)roken | |
| *-D.in - Reconstructing should yield (D)ifferent data | |
| *-E.in - CXER reconstruction should yield byte-wise identical data. | |
| *-X.in - CXER reconstruction should yield non-identical data. | |
| Otherwise, a reconstructed buffer should loosely match the original. |
