Openssl error 0x02001005 and 0x2006D002 on Windows?

Question

I'm trying to convert a .cer cert to a .p12 one using opensll.

this is the command that I'm using

C:\OpenSSL-Win32\bin>openssl x509 -inform der -in developer_identity.cer -out de
veloper_identity.pem

I'm conitunally getting an error and I don't know what it means. How can I figure out how to fix it.

2104:error:02001005:system library:fopen:Input/output error:.\crypto\bio\bss_fil
e.c:163:fopen('C:\OpenSSL-Win32\bin','rb')
2104:error:2006D002:BIO routines:BIO_new_file:system lib:.\crypto\bio\bss_file.c
:168:
2104:error:0E078002:configuration file routines:DEF_LOAD:system lib:.\crypto\con
f\conf_def.c:199:

EDIT 1

I'm not entirely sure if I'm using it correctly so I'll outline what I tried.

1) Downloaded openssl.exe and installed it.

2) Copied the cert file I want to work with to the bin folder in the install location.

3) Entered the command at the top of this post

Answer 1

I had the same problem. I resolved with the above answer.

Just type depending on 32 o 64 bits:

C:> set OPENSSL_CONF=C:\OpenSSL-Win32\bin\openssl.cfg

or

C:> set OPENSSL_CONF=C:\OpenSSL-Win64\bin\openssl.cfg

Thanks.

Answer 2

 C:\OpenSSL-Win32\bin

Looks like it's trying to open a directory for reading? Does openssl work generally or is there some problem with its installation?
