svn_x509_certinfo_t* svn_x509_certinfo_dup ( const svn_x509_certinfo_t certinfo,
apr_pool_t *  result_pool,
apr_pool_t *  scratch_pool 
)

Returns a deep copy of certinfo, allocated in result_pool.

May use scratch_pool for temporary allocations.

Since
New in 1.9.
const svn_checksum_t* svn_x509_certinfo_get_digest ( const svn_x509_certinfo_t certinfo)

Returns the digest (fingerprint) from certinfo.

Since
New in 1.9.
const apr_array_header_t* svn_x509_certinfo_get_hostnames ( const svn_x509_certinfo_t certinfo)

Returns an array of (const char*) host names from certinfo.

Since
New in 1.9.
const char* svn_x509_certinfo_get_issuer ( const svn_x509_certinfo_t certinfo,
apr_pool_t *  result_pool 
)

Returns the cerficiate issuer DN from certinfo.

Since
New in 1.9.
const apr_array_header_t* svn_x509_certinfo_get_issuer_attrs ( const svn_x509_certinfo_t certinfo)

Returns a list of the attributes for the issuer in the certinfo.

Each member of the list is of type svn_x509_name_attr_t.

Since
New in 1.9.
const char* svn_x509_certinfo_get_subject ( const svn_x509_certinfo_t certinfo,
apr_pool_t *  result_pool 
)

Returns the subject DN from certinfo.

Since
New in 1.9.
const apr_array_header_t* svn_x509_certinfo_get_subject_attrs ( const svn_x509_certinfo_t certinfo)

Returns a list of the attributes for the subject in the certinfo.

Each member of the list is of type svn_x509_name_attr_t.

Since
New in 1.9.
apr_time_t svn_x509_certinfo_get_valid_from ( const svn_x509_certinfo_t certinfo)

Returns the start of the certificate validity period from certinfo.

Since
New in 1.9.
const apr_time_t svn_x509_certinfo_get_valid_to ( const svn_x509_certinfo_t certinfo)

Returns the end of the certificate validity period from certinfo.

Since
New in 1.9.
svn_x509_name_attr_t* svn_x509_name_attr_dup ( const svn_x509_name_attr_t attr,
apr_pool_t *  result_pool,
apr_pool_t *  scratch_pool 
)

Returns a deep copy of the attr, allocated in result_pool.

May use scratch_pool for temporary allocations.

Since
New in 1.9.
const unsigned char* svn_x509_name_attr_get_oid ( const svn_x509_name_attr_t attr,
apr_size_t *  len 
)

Returns the OID of attr as encoded in the certificate.

The length of the OID will be set in len.

Since
New in 1.9.
const char* svn_x509_name_attr_get_value ( const svn_x509_name_attr_t attr)

Returns the value of attr as a UTF-8 C string.

Since
New in 1.9.
const char* svn_x509_oid_to_string ( const unsigned char *  oid,
apr_size_t  oid_len,
apr_pool_t *  scratch_pool,
apr_pool_t *  result_pool 
)

Given an oid return a null-terminated C string representation.

For example an OID with the bytes "\x2A\x86\x48\x86\xF7\x0D\x01\x09\x01" would be converted to the string "1.2.840.113549.1.9.1". Returns NULL if the can't be represented as a string.

Since
New in 1.9.
svn_error_t* svn_x509_parse_cert ( svn_x509_certinfo_t **  certinfo,
const char *  buf,
apr_size_t  buflen,
apr_pool_t *  result_pool,
apr_pool_t *  scratch_pool 
)

Parse x509 der certificate data from buf with length buflen and return certificate information in *certinfo, allocated in result_pool.

Note
This function has been written with the intent of display data in a certificate for a user to see. As a result, it does not do much validation on the data it parses from the certificate. It does not for instance verify that the certificate is signed by the issuer. It does not verify a trust chain. It does not error on critical extensions it does not know how to parse. So while it can be used as part of a certificate validation scheme, it can't be used alone for that purpose.
