Hello, I am trying to load a certificate and private key. (both are .der file). The private key is unencrypted. The certificate file is loaded using
SSL_CTX_use_certificate_file(ctx, "cert.der", SSL_FILETYPE_ASN1) which is sucessful. Then I try to load private key file using SSL_CTX_use_PrivateKey_file(ctx,"privatekey.der",SSL_FILETYPE_ASN1) which is returning error(0) and outputs 31061:error:0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag:tasn_dec.c:1316: 31061:error:0D06C03A:asn1 encoding routines:ASN1_D2I_EX_PRIMITIVE:nested asn1 error:tasn_dec.c:828: 31061:error:0D08303A:asn1 encoding routines:ASN1_TEMPLATE_NOEXP_D2I:nested asn1 error:tasn_dec.c:748:Field=n, Type=RSA 31061:error:0D09A00D:asn1 encoding routines:d2i_PrivateKey:ASN1 lib:d2i_pr.c:99: 31061:error:140B000D:SSL routines:SSL_CTX_use_PrivateKey_file:ASN1 lib:ssl_rsa.c:669: I then used the command "openssl pkcs8 -in sigkey.der -inform DER -nocrypt -out private.pem". The PEM file generated is then loaded using SSL_CTX_use_PrivateKey_file(ctx,"private.pem",SSL_FILETYPE_PEM) and this is successful. What is the problem in using the private key file in .der format? I am using *"openssl-0.9.8".* Regards Aravind GJ
