    <p>I'm receiving a String containing a PEM encoded X.509 certificate from somewhere. I'd like to import this certificate into the KeyChain of iOS. </p> <p>I'm planning to do the following:</p> <ol> <li>convert NSString to openssl X509</li> <li>create PKCS12 </li> <li>convert PKCS12 to NSData</li> <li>import NSData with SecPKCS12Import</li> </ol> <p>So far I came up with the following code:</p> <pre><code>const char *cert_chars = [certStr cStringUsingEncoding:NSUTF8StringEncoding]; BIO *buffer = BIO_new(BIO_s_mem()); BIO_puts(buffer, cert_chars); X509 *cert; cert = PEM_read_bio_X509(buffer, NULL, 0, NULL); if (cert == NULL) { NSLog(@"error"); } X509_print_fp(stdout, cert); EVP_PKEY *privateKey; const unsigned char *privateBits = (unsigned char *) [privateKeyData bytes]; int privateLength = [privateKeyData length]; privateKey = d2i_AutoPrivateKey(NULL, &amp;privateBits, privateLength); if (!X509_check_private_key(cert, privateKey)) { NSLog(@"PK error"); } PKCS12 *p12 = PKCS12_create("test", "David's Cert", privateKey, cert, NULL, 0, 0, 0, 0, 0); </code></pre> <p>Unfortunately, p12 is nil even though X509_check_private_key was successful and X509_print_fp(stdout, cert) prints a valid certificate.</p> <ol> <li>is my approach correct</li> <li>how come PKCS12_create seems to fail? </li> </ol> <p><strong>Update:</strong></p> <p>The call PKCS12_create seems to fail in the following method:</p> <pre><code>int EVP_PBE_CipherInit(ASN1_OBJECT *pbe_obj, const char *pass, int passlen, ASN1_TYPE *param, EVP_CIPHER_CTX *ctx, int en_de) { const EVP_CIPHER *cipher; const EVP_MD *md; int cipher_nid, md_nid; EVP_PBE_KEYGEN *keygen; if (!EVP_PBE_find(EVP_PBE_TYPE_OUTER, OBJ_obj2nid(pbe_obj), &amp;cipher_nid, &amp;md_nid, &amp;keygen)) { char obj_tmp[80]; EVPerr(EVP_F_EVP_PBE_CIPHERINIT,EVP_R_UNKNOWN_PBE_ALGORITHM); if (!pbe_obj) BUF_strlcpy (obj_tmp, "NULL", sizeof obj_tmp); else i2t_ASN1_OBJECT(obj_tmp, sizeof obj_tmp, pbe_obj); ERR_add_error_data(2, "TYPE=", obj_tmp); return 0; } if(!pass) passlen = 0; else if (passlen == -1) passlen = strlen(pass); if (cipher_nid == -1) cipher = NULL; else { cipher = EVP_get_cipherbynid(cipher_nid); if (!cipher) { EVPerr(EVP_F_EVP_PBE_CIPHERINIT,EVP_R_UNKNOWN_CIPHER); return 0; } } if (md_nid == -1) md = NULL; else { md = EVP_get_digestbynid(md_nid); if (!md) { EVPerr(EVP_F_EVP_PBE_CIPHERINIT,EVP_R_UNKNOWN_DIGEST); return 0; } } if (!keygen(ctx, pass, passlen, param, cipher, md, en_de)) { EVPerr(EVP_F_EVP_PBE_CIPHERINIT,EVP_R_KEYGEN_FAILURE); return 0; } return 1; } </code></pre> <p>Retrieving the cipher </p> <pre><code>cipher = EVP_get_cipherbynid(cipher_nid); </code></pre> <p>somehow returns nil for "RC2-40-CBC".</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
