Detailed Description

Author:

Sam Lang

The proxypolicy set of data structures and functions provides an interface to generating a PROXYPOLICY structure which is maintained as a field in the PROXYCERTINFO structure, and ultimately gets written to a DER encoded string.

Further Information about proxy policies is available in the X.509 Proxy Certificate Profile document.

Function Documentation

ASN1_METHOD* PROXYPOLICY_asn1_meth ()

Creates an ASN1_METHOD structure, which contains pointers to routines that convert any PROXYPOLICY structure to its associated ASN1 DER encoded form and vice-versa.

Returns:

the ASN1_METHOD object

PROXYPOLICY* PROXYPOLICY_new ()

Allocates and initializes a new PROXYPOLICY structure.

Returns:

pointer to the new PROXYPOLICY

void PROXYPOLICY_free (PROXYPOLICY * policy)

Frees a PROXYPOLICY.

Parameters:

policy the proxy policy to free

PROXYPOLICY* PROXYPOLICY_dup (PROXYPOLICY * policy)

Makes a copy of the proxypolicy - this function allocates space for a new PROXYPOLICY, so the returned PROXYPOLICY must be freed when its no longer needed.

Parameters:

policy the proxy policy to copy

Returns:

the new PROXYPOLICY

int PROXYPOLICY_cmp (const PROXYPOLICY * a, const PROXYPOLICY * b)

Compares two PROXYPOLICY structs for equality This function first compares the policy language numeric id's, if they're equal, it then compares the two policies.

Returns:

0 if equal, nonzero if not

int PROXYPOLICY_print (BIO * bp, PROXYPOLICY * policy)

Prints the PROXYPOLICY struct using the BIO stream.

Parameters:

bp the BIO stream to print to
policy the PROXYPOLICY to print

Returns:

1 on success, 0 on error

int PROXYPOLICY_print_fp (FILE * fp, PROXYPOLICY * policy)

Prints the PROXYPOLICY to the file stream FILE*.

Parameters:

fp the FILE* stream to print to
policy the PROXYPOLICY to print

Returns:

number of bytes printed, -2 or -1 on error

int PROXYPOLICY_set_policy_language (PROXYPOLICY * policy, ASN1_OBJECT * policy_language)

Sets the policy language of the PROXYPOLICY.

Parameters:

policy the PROXYPOLICY to set the policy language of
policy_language the policy language to set it to

Returns:

1 on success, 0 on error

ASN1_OBJECT* PROXYPOLICY_get_policy_language (PROXYPOLICY * policy)

Gets the policy language of the PROXYPOLICY.

Parameters:

policy the proxy policy to get the policy language of

Returns:

the policy language as an ASN1_OBJECT

int PROXYPOLICY_set_policy (PROXYPOLICY * proxypolicy, unsigned char * policy, int length)

Sets the policy of the PROXYPOLICY.

Parameters:

proxypolicy the proxy policy to set the policy of
policy the policy to set it to
length the length of the policy

Returns:

1 on success, 0 on error

unsigned char* PROXYPOLICY_get_policy (PROXYPOLICY * policy, int * length)

Gets the policy of a PROXYPOLICY.

Parameters:

policy the PROXYPOLICY to get the policy of
length the length of the returned policy - this value gets set by this function

Returns:

the policy

int i2d_PROXYPOLICY (PROXYPOLICY * a, unsigned char ** pp)

Converts a PROXYPOLICY from its internal structure to a DER encoded form.

Parameters:

a the PROXYPOLICY to convert
pp the buffer to put the DER encoding in

Returns:

the length of the DER encoding in bytes

PROXYPOLICY* d2i_PROXYPOLICY (PROXYPOLICY ** a, unsigned char ** pp, long length)

Converts the PROXYPOLICY from its DER encoded form to an internal PROXYPOLICY structure.

Parameters:

a the PROXYPOLICY struct to set
pp the DER encoding to get the PROXYPOLICY from
length the length of the DER encoding

Returns:

the resulting PROXYPOLICY in its internal structure form - this variable has been allocated using _new routines, so it needs to be freed once its no longer used
