System and method of mobile lightweight cryptographic directory access

A handler system for accessing cryptographic data stored in a Lightweight Directory Access Protocol (LDAP) server, the handler system comprising a processing device for executing computer readable instructions that, when executed, cause the handler system to:

• determine whether a data item to be transmitted to a client system includes a digital signature requiring cryptographic data for verification;
• after determining that the data item includes a digital signature, generate LDAP query data, the LDAP query data corresponding to a LDAP query for the cryptographic data;
• execute the LDAP query;
• receive the cryptographic data from the LDAP server in response to the LDAP query in multiple passes;
• and
• upon completion of the execution of the LDAP query, provide the cryptographic data for transmission to the client system in a single pass.

A non-transitory computer readable medium having tangibly stored thereon instructions executable by a handler system for accessing cryptographic data stored in a Lightweight Directory Access Protocol (LDAP) server, the instructions, when executed by the handler system, causing the handler system to:

• determine whether a data item to be transmitted to a client system includes a digital signature requiring cryptographic data for verification;
• after determining that the data item includes a digital signature, generate LDAP query data, the LDAP query data corresponding to a LDAP query for the cryptographic data;
• execute the LDAP query;
• receive the cryptographic data from the LDAP server in response to the LDAP query in multiple passes;
• and
• upon completion of the execution of the LDAP query, provide the cryptographic data for transmission to the client system in a single pass.
