  2. =head1 NAME
  3. PKCS12_create - create a PKCS#12 structure
  4. =head1 SYNOPSIS
  5. #include <openssl/pkcs12.h>
  6. PKCS12 *PKCS12_create(const char *pass, const char *name, EVP_PKEY *pkey,
  7. X509 *cert, STACK_OF(X509) *ca,
  8. int nid_key, int nid_cert, int iter, int mac_iter, int keytype);
  9. =head1 DESCRIPTION
  10. PKCS12_create() creates a PKCS#12 structure.
  11. B<pass> is the passphrase to use. B<name> is the B<friendlyName> to use for
  12. the supplied certificate and key. B<pkey> is the private key to include in
  13. the structure and B<cert> its corresponding certificates. B<ca>, if not B<NULL>
  14. is an optional set of certificates to also include in the structure.
  15. B<nid_key> and B<nid_cert> are the encryption algorithms that should be used
  16. for the key and certificate respectively. The modes
  17. GCM, CCM, XTS, and OCB are unsupported. B<iter> is the encryption algorithm
  18. iteration count to use and B<mac_iter> is the MAC iteration count to use.
  19. B<keytype> is the type of key.
  20. =head1 NOTES
  21. The parameters B<nid_key>, B<nid_cert>, B<iter>, B<mac_iter> and B<keytype>
  22. can all be set to zero and sensible defaults will be used.
  23. These defaults are: 40 bit RC2 encryption for certificates, triple DES
  24. encryption for private keys, a key iteration count of PKCS12_DEFAULT_ITER
  25. (currently 2048) and a MAC iteration count of 1.
  26. The default MAC iteration count is 1 in order to retain compatibility with
  27. old software which did not interpret MAC iteration counts. If such compatibility
  28. is not required then B<mac_iter> should be set to PKCS12_DEFAULT_ITER.
  29. B<keytype> adds a flag to the store private key. This is a non standard extension
  30. that is only currently interpreted by MSIE. If set to zero the flag is omitted,
  31. if set to B<KEY_SIG> the key can be used for signing only, if set to B<KEY_EX>
  32. it can be used for signing and encryption. This option was useful for old
  33. export grade software which could use signing only keys of arbitrary size but
  34. had restrictions on the permissible sizes of keys which could be used for
  35. encryption.
  36. If a certificate contains an B<alias> or B<keyid> then this will be
  37. used for the corresponding B<friendlyName> or B<localKeyID> in the
  38. PKCS12 structure.
  39. Either B<pkey>, B<cert> or both can be B<NULL> to indicate that no key or
  40. certificate is required. In previous versions both had to be present or
  41. a fatal error is returned.
  42. B<nid_key> or B<nid_cert> can be set to -1 indicating that no encryption
  43. should be used.
  44. B<mac_iter> can be set to -1 and the MAC will then be omitted entirely.
  45. PKCS12_create() makes assumptions regarding the encoding of the given pass
  46. phrase.
  47. See L<passphrase-encoding(7)> for more information.
  48. =head1 RETURN VALUES
  49. PKCS12_create() returns a valid B<PKCS12> structure or NULL if an error occurred.
