Returns: _wsse__UsernameToken object or NULL Note: this release supports the use of at most one UsernameToken in the header.

int soap_wsse_verify_auto | ( | struct soap * | soap,
|  | int | alg,
|  | const void * | key,
|  | size_t | keylen
| ) |

  | Uses the wsse plugin to initiate the automatic verification of the signature and SignedInfo Reference digests. Parameters:
  | soap | context
  `[in]` | alg | to verify signature if signature has no secret or public key, use SOAP_SMD_NONE to omit
  `[in]` | key | is HMAC key or EVP_PKEY or NULL
  `[in]` | keylen | is HMAC key length or 0
Returns: SOAP_OK This function does not actually verify the message, but initiates the plugin's algorithm to store the message in a DOM to automatically verify the signature and digests. If the message does not contain a key to verify the signature, the alg, key, and keylen parameters are used. It is important that the X509 certificate used to verify the signature, which requires soap->cafile and/or soap->capath to be set.

int soap_wsse_verify_body | ( | struct soap * | soap | ) |

  | Post-checks the presence of signed SOAP Body. Does not verify the signature of the Body, which is done with soap_wee_verify_auto. Parameters:
  | soap | context
Returns: SOAP_OK (signed) or SOAP_ERR This function does not actually verify the signature of the Body. It checks whether the Body is signed and thus its integrity is preserved. Clients should call this function after invocation. Services should call this function inside a service operation. This function traverses the entire DOM, so performance is determined by the size of a message.

int soap_wsse_verify_digest | ( | struct soap * | soap,
|  | int | alg,
|  | int | canonical,
|  | const char * | id,
|  | unsigned char | hash[SOAP_SMD_MAX_SIZE]
| ) |

  | Verifies the digest value of an XML element referenced by id against the hash. Parameters:
  | soap | context
  `[in]` | alg | digest algorithm
  `[in]` | canonical | flag indicating that element is signed in exc-c14n form
  `[in]` | id | string of the XML element to verify
  `[in]` | hash | digest value to verify against
Returns: SOAP_OK or fault

int soap_wsse_verify_done | ( | struct soap * | soap | ) |

  | Terminates the automatic verification of signatures. Parameters:
  | soap | context
Returns: SOAP_OK

size_t soap_wsse_verify_element | ( | struct soap * | soap,
|  | const char * | URI,
|  | const char * | tag
| ) |

  | Post-checks the presence of signed element(s). Does not verify the signature of these elements, which is done with soap_wee_verify_auto. Parameters:
  | soap | context
  | URI | namespace of element(s)
  | tag | name of element(s)
Returns: number of matching elements signed. This function does not actually verify the signature of each element, but checks whether the elements are signed and thus their integrity is preserved. Signed element nesting rules are obeyed, so if the matching element is a descendent of a signed element, it is signed as well. Thus, the verification process follows nesting rules. Client should call this function after invocation. Services should call this function inside a service operation. This function traverses the entire DOM, so performance is determined by the size of a message. To check the SOAP Body (either using SOAP 1.1 or 1.2), soap_wsse_verify_element(soap, namespaces[0].ns, "Body"). To check whether the Timestamp was signed (assuming it is present and message expiration checked with soap_wsse_verify_Timestamp), use soap_wsse_verify_element(soap, "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd", "Timestamp"). Note: for future releases XPath queries (or forms of these) will be considered.

int soap_wsse_verify_init | ( | struct soap * | soap | ) |

  | Uses the wsse plugin to initiate the verification of the signature and SignedInfo Reference digests. Parameters:
  | soap | context
Returns: SOAP_OK This function does not actually verify the message, but initiates the plugin's data to store the message in a DOM to verify the signature. The signature and digests in the DOM must be verified manually.

size_t soap_wsse_verify_nested | ( | struct soap * | soap,
|  | struct soap_dom_element * | dom,
|  | const char * | URI,
|  | const char * | tag
| ) | `[static]`

  | Counts signed matching elements from the dom node and down. Parameters:
  | soap | context
  | dom | node to check and down
  | URI | namespace of element(s)
  | tag | name of element(s)
Returns: number of matching elements.

int soap_wsse_verify_Password | ( | struct soap * | soap,
|  | const char * | password
| ) |

  | Verifies the supplied password or sets wsse:FailedAuthentication fault. Parameters:
  | soap | context
  `[in]` | password | string to verify against
Returns: SOAP_OK (authorized) or SOAP_FAULT with wsse:FailedAuthentication fault The verification supports both clear-text password verification and digest password authentication. For digest authentication a history mechanism with a digest authentication session database ensures protection against replay attacks. Note: this release supports the use of at most one UsernameToken in the header.

int soap_wsse_verify_SignatureValue | ( | struct soap * | soap,
|  | int | alg,
|  | const void * | key,
|  | int | keylen
| ) |

  | Verifies the SignatureValue of a SignedInfo element. Parameters:
  | soap | context
  `[in]` | alg | is SOAP_SMD_HMAC_SHA1, SOAP_SMD_VRFY_DSA_SHA1, or SOAP_SMD_VRFY_RSA_SHA1 determined by the SignedInfo/SignatureMethod
  `[in]` | key | to use to verify (HMAC or EVP_PKEY)
  `[in]` | keylen | length of HMAC key
Returns: SOAP_OK, SOAP_EOM, or fault This function searches for the SignedInfo element in the soap->dom DOM tree to verify the signature in the SignatureValue element. Using the DOM ensures we will verify the signature of a SignedInfo as it was exactly received by the parser, by using the -DWITH_DOM compile flag and SOAP_XML_DOM runtime flag. If there is no DOM, it verifies the signature of the deserialized SignedInfo element in the SOAP Header. However, serializing deserialized data may change the octet stream that was signed, unless we're using gSOAP as producers and consumers (with the SOAP_XML_INDENT flag reset).

int soap_wsse_verify_SignedInfo | ( | struct soap * | soap | ) |

  | Verifies the digest values of the XML elements referenced by the SignedInfo References. Parameters:
  | soap | context
Returns: SOAP_OK or fault This function searches for the SignedInfo element in the soap->dom DOM tree to verify the digests contained therein. Using the DOM ensures we will verify the digests of the locally signed elements as they were exactly received by the parser, by using the -DWITH_DOM compile flag and SOAP_XML_DOM runtime flag. If there is no DOM, the function fails.

int soap_wsse_verify_Timestamp | ( | struct soap * | soap | ) |

  | Verifies the Timestamp/Expires element against the current time. Parameters:
  | soap | context
Returns: SOAP_OK or SOAP_FAULT with wsse:FailedAuthentication fault Sets wsse:FailedAuthentication fault if wsu:Timestamp is expired. The SOAP_WSSE_CLKSKEW value is used as a margin to mitigate clock skew. Keeps silent when no timestamp is supplied or no expiration date is included in the wsu:Timestamp element.

int soap_wsse_verify_X509 | ( | struct soap * | soap,
|  | X509 * | cert
| ) |

  | Verifies X509 certificate against soap->cafile, soap->capath, and soap->crlfile. Parameters:
  | soap | context
  `[in]` | cert | X509 certificate
Returns: SOAP_OK or fault This is an expensive operation. Whenever a new soap context is created, the cafile and objects are loaded into that context each time we need to verify a certificate.
