Hi again,
I forgot to include a subject and I have some extra information on this as well so thought I'd send more. I have printed out the human readable error output of the call to PEM_read_PrivateKey and it is a s such: error:0906B072:lib(9):func(107):reason(114) >From looking through the EVP error codes function 107 is PEM_GET_EVP_CIPHER_INFO and reason 114 is PEM_R_UNSUPPORTED_ENCRYPTION. Now I created the private key using OpenSSL so it seems odd to me that it would be considered unsupported. Some relevant info from the key file is: Proc-Type: 4,ENCRYPTED DEK-Info: DES-EDE3-CBC,C1897FAC7F2375FD I have read that the cipher type is determined from the salt, i.e. C1897..., and a few other variables such as iv (?) that I haven't had much luck in determining. Any ideas why PEM_read_PrivateKey would still be returning NULL??? By the way I am using version 0.9.8g which I know is slightly outdated if that makes a difference. -John Larson ________________________________ From: owner-openssl-us...@openssl.org [mailto:owner-openssl-us...@openssl.org] On Behalf Of Larson, John Sent: Monday, February 23, 2009 5:17 PM To: openssl-users@openssl.org Subject: Hi all, I am working on some code that takes an existing EC Private Key stored in a PEM file and uses it to create a digital signature. In my code the call I make to read the private key continues to return a NULL pointer. I perform the call as such: pkey = PEM_read_PrivateKey(keyFile, NULL, NULL, "password"); I have confirmed both that I am referencing the correct file and that the pass phrase I use ("password" in this example) is correct. I confirmed the password by executing on the command line: openssl ec -in signer_key.pem -passin pass:password Any ideas why my function call would still return NULL?
