  41 =head1 DESCRIPTION
  42
  43 OSSL_CRMF_MSG_set0_validity() sets the I<notBefore> and I<notAfter> fields
  44 as validity constraints in the certTemplate of I<crm>.
  45 Any of the I<notBefore> and I<notAfter> parameters may be NULL,
  46 which means no constraint for the respective field.
  47 On success ownership of I<notBefore> and I<notAfter> is transferred to I<crm>.
  48
  49 OSSL_CRMF_MSG_set_certReqId() sets I<rid> as the certReqId of I<crm>.
  50
  51 OSSL_CRMF_CERTTEMPLATE_fill() sets those fields of the certTemplate I<tmpl>
  52 for which non-NULL values are provided: I<pubkey>, I<subject>, I<issuer>,
  53 and/or I<serial>.
  54 X.509 extensions may be set using OSSL_CRMF_MSG_set0_extensions().
  55 On success the reference counter of the I<pubkey> (if given) is incremented,
  56 while the I<subject>, I<issuer>, and I<serial> structures (if given) are copied.
  57
  58 OSSL_CRMF_MSG_set0_extensions() sets I<exts> as the extensions in the
  59 certTemplate of I<crm>. Frees any pre-existing ones and consumes I<exts>.
  60
  61 OSSL_CRMF_MSG_push0_extension() pushes the X509 extension I<ext> to the
  62 extensions in the certTemplate of I<crm>.  Consumes I<ext>.
  63
  64 OSSL_CRMF_MSG_create_popo() creates and sets the Proof-of-Possession (POPO)
  65 according to the method I<meth> in I<crm>.<
  66 The library context I<libctx> and property query string I<propq>,
  67 may be NULL to select the defaults.
  68 In case the method is OSSL_CRMF_POPO_SIGNATURE the POPO is calculated
  69 using the private key I<pkey> and the digest method I<digest>.
  70
  71 I<meth> can be one of the following:
  72
  73 =over 8
  74
  75 =item * OSSL_CRMF_POPO_NONE       - RFC 4211, section 4, POP field omitted.
  76 CA/RA uses out-of-band method to verify POP. Note that servers may fail in this
  77 case, resulting for instance in HTTP error code 500 (Internal error).
  78
  79 =item * OSSL_CRMF_POPO_RAVERIFIED - RFC 4211, section 4, explicit indication
  80 that the RA has already verified the POP.
  81
  82 =item * OSSL_CRMF_POPO_SIGNATURE  - RFC 4211, section 4.1, only case 3 supported
  83 so far.
  84
  85 =item * OSSL_CRMF_POPO_KEYENC     - RFC 4211, section 4.2, only indirect method
  86 (subsequentMessage/enccert) supported,
  87 challenge-response exchange (challengeResp) not yet supported.
  88
  89 =item * OSSL_CRMF_POPO_KEYAGREE   - RFC 4211, section 4.3, not yet supported.

  93 OSSL_CRMF_MSGS_verify_popo verifies the Proof-of-Possession of the request with
  94 the given I<rid> in the list of I<reqs>. Optionally accepts RAVerified. It can
  95 make use of the library context I<libctx> and property query string I<propq>.

  98
  99 All functions return 1 on success, 0 on error.
