Function Documentation

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

Initiates a digest or signature computation.

Parameters
soapcontext
[in]algis the digest or signature (sign/verification) algorithm used
[in]keyis a HMAC key or pointer to EVP_PKEY object or NULL for digests
[in]keylenis 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
soapcontext
[in,out]datasmdevp 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
soapcontext
[in]bufcontains signature for verification (when using a SOAP_SMD_VRFY algorithm) or NULL for cleanup
[out]bufis populated with the digest or signature with maximum length soap_smd_size(alg, key)
[in]lenpoints to length of signature to verify (when using a SOAP_SMD_VRFY algorithm) or NULL for cleanup
[out]lenpoints 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
soapcontext
[in,out]datasmdevp engine context
[in]bufcontains signature for verification (SOAP_SMD_VRFY algorithms) maximum length soap_smd_size(alg, key)
[out]bufis populated with the digest or signature of
[in]lenpoints to length of signature to verify (SOAP_SMD_VRFY algorithms)
[out]lenpoints 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
soapcontext
[in,out]datasmdevp engine context
[in]algis algorithm to use
[in]keyis key to use or NULL for digests
[in]keylenis 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]algis the digest or signature algorithm to be used
[in]keyis 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
soapcontext
[in,out]datasmdevp engine context
[in]bufcontains message part
[in]lenof message part
Returns
SOAP_OK or SOAP_SSL_ERROR
