borg benchmark cpu
fails with libressl
`borg benchmark cpu` fails on OpenBSD with the error below, which is caused by LibreSSL currently not supporting AES256_OCB and CHACHA20_POLY1305. Work around this by checking if borg is used with LibreSSL. Tested on OpenBSD. ``` Chunkers ======================================================= buzhash,19,23,21,4095 1GB 14.294s fixed,1048576 1GB 0.244s Non-cryptographic checksums / hashes =========================== crc32 (libdeflate, used) 1GB 0.724s crc32 (zlib) 1GB 1.953s xxh64 1GB 0.361s Cryptographic hashes / MACs ==================================== hmac-sha256 1GB 7.039s blake2b-256 1GB 9.845s Encryption ===================================================== aes-256-ctr-hmac-sha256 1GB 18.312s aes-256-ctr-blake2b 1GB 21.213s Local Exception Traceback (most recent call last): File "/usr/local/lib/python3.9/site-packages/borg/archiver.py", line 5241, in main exit_code = archiver.run(args) File "/usr/local/lib/python3.9/site-packages/borg/archiver.py", line 5172, in run return set_ec(func(args)) File "/usr/local/lib/python3.9/site-packages/borg/archiver.py", line 607, in do_benchmark_cpu print(f"{spec:<24} {size:<10} {timeit(func, number=100):.3f}s") File "/usr/local/lib/python3.9/timeit.py", line 233, in timeit return Timer(stmt, setup, timer, globals).timeit(number) File "/usr/local/lib/python3.9/timeit.py", line 177, in timeit timing = self.inner(it, self.timer) File "<timeit-src>", line 6, in inner File "/usr/local/lib/python3.9/site-packages/borg/archiver.py", line 602, in <lambda> ("aes-256-ocb", lambda: AES256_OCB( File "src/borg/crypto/low_level.pyx", line 636, in borg.crypto.low_level.AES256_OCB.__init__ File "src/borg/crypto/low_level.pyx", line 633, in borg.crypto.low_level.AES256_OCB.requirements_check ValueError: AES OCB is not implemented by LibreSSL (yet?).
