We've run into an interesting - apparently new? - behavior of the openssl ca command:
I believe we've used the following command in the past (pre 1.0.0). (Don't know why we were still using the -infiles option with a single input file - something vestigial, no doubt; Nonetheless, I think it's worked: ../bin/openssl ca \ -days 1095 \ -infiles YOUR.csr \ -out YOUR.crt \ -config ../openssl.cnf Now, using OpenSSL v1.0.0, this command results in an error, as if the -infiles option is trying to read the -out option as a filename! (Yes, many of our commands are formatted with the backslash for readability): -out: No such file or directory 4274892676:error:02001002:system library:fopen:No such file or directory:bss_file.c:355:fopen('-out','r') 4274892676:error:20074002:BIO routines:FILE_CTRL:system lib:bss_file.c:357: Don't know if this is a new 'fastidiousness' of the ca command, or if we simply never hit it before, but it may merit attention. For example, we haven't tested all the permutations, such as what would happen if the -infiles option were the last option in the command string, and had only one file as an input? Lou
