## Function Documentation

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

Initiates a digest or signature computation.

Parameters

  | soap | context
  [in] | alg | is the digest or signature (sign/verification) algorithm used
  [in] | key | is a HMAC key or pointer to EVP_PKEY object or NULL for digests
  [in] | keylen | is the length of the HMAC key or 0

Returns
  SOAP_OK, SOAP_EOM, or SOAP_SSL_ERROR

void soap_smd_cleanup | ( | struct soap * | soap,
|  | struct soap_smd_data * | data
| ) |  |

Clear (signed) digest computation and delete context.

Parameters

  | soap | context
  [in,out] | data | smdevp engine context

int soap_smd_end | ( | struct soap * | soap,
|  | char * | buf,
|  | int * | len
| ) |  |

Completes a digest or signature computation. Also deallocates temporary storage allocated by soap_smd_begin(), so MUST be called after soap_smd_begin().

Parameters

  | soap | context
  [in] | buf | contains signature for verification (when using a SOAP_SMD_VRFY algorithm) or NULL for cleanup
  [out] | buf | is populated with the digest or signature with maximum length soap_smd_size(alg, key)
  [in] | len | points to length of signature to verify (when using a SOAP_SMD_VRFY algorithm) or NULL for cleanup
  [out] | len | points to length of stored digest or signature (when not NULL)

Returns
  SOAP_OK, SOAP_USER_ERROR, or SOAP_SSL_ERROR

int soap_smd_final | ( | struct soap * | soap,
|  | struct soap_smd_data * | data,
|  | char * | buf,
|  | int * | len
| ) |  |

Finalizes (signed) digest computation, delete context and returns digest or signature.

Parameters

  | soap | context
  [in,out] | data | smdevp engine context
  [in] | buf | contains signature for verification (SOAP_SMD_VRFY algorithms) maximum length soap_smd_size(alg, key)
  [out] | buf | is populated with the digest or signature of
  [in] | len | points to length of signature to verify (SOAP_SMD_VRFY algorithms)
  [out] | len | points to length of stored digest or signature (pass NULL if you are not interested in this value)

Returns
  SOAP_OK or SOAP_SSL_ERROR

int soap_smd_init | ( | struct soap * | soap,
|  | struct soap_smd_data * | data,
|  | int | alg,
|  | const void * | key,
|  | int | keylen
| ) |  |

Initiates a (signed) digest computation.

Parameters

  | soap | context
  [in,out] | data | smdevp engine context
  [in] | alg | is algorithm to use
  [in] | key | is key to use or NULL for digests
  [in] | keylen | is length of HMAC key (when provided)

Returns
  SOAP_OK or SOAP_SSL_ERROR

size_t soap_smd_size | ( | int | alg,
|  | const void * | key
| ) |  |

Returns the number of octets needed to store the digest or signature returned by soap_smd_end.

Parameters

  [in] | alg | is the digest or signature algorithm to be used
  [in] | key | is a pointer to an EVP_PKEY object for RSA/DSA signatures or NULL for digests and HMAC

Returns
  size_t number of octets that is needed to hold digest or signature

See also
  soap_smd_end

The values returned for digests are SOAP_SMD_MD5_SIZE, SOAP_SMD_SHA1_SIZE, SOAP_SMD_SHA256_SIZE, SOAP_SMD_SHA512_SIZE.

int soap_smd_update | ( | struct soap * | soap,
|  | struct soap_smd_data * | data,
|  | const char * | buf,
|  | size_t | len
| ) |  |

Updates (signed) digest computation with message part.

Parameters

  | soap | context
  [in,out] | data | smdevp engine context
  [in] | buf | contains message part
  [in] | len | of message part

Returns
  SOAP_OK or SOAP_SSL_ERROR
