Chapter 10 Secure Certificate 

 

Section 10.5 Secure Certificate Descriptor Sections 

Note:  

All lines within the secure certificate text file are terminated with a character 

sequence carriage return followed by line feed (e.g., <cr><lf>) except for the last line of the 
file. 

The fields of the file are described more fully in the sections that follow. 

10.5 

The following descriptor sections make up a secure certificate: 

 

Secure certificate MAC descriptor section 

 

Visa PED mode descriptor section 

 

Application descriptor section 

 

Secure file descriptor section 

 

Non-secure file descriptor section 

 

Delete application code file descriptor section 

 

Delete data file descriptor section 

 

Delete the whole application descriptor section 

10.5.1 

This section, which is the MAC of the secure certificate file, must exist on the first line of the 
file. If it does not, validation fails. If it does, a MAC is calculated on the secure certificate, 
using SHA1 + MAC, starting from the first character of the second line of the file until the 
end of the file. 

If the MAC detected on the first line of the file is not the same as the calculated MAC, 
validation fails. 

The first line of the file must be in the following format:  

MAC=12345678   

The first field of the application descriptor is the MAC for the secure certificate file itself.   

 

MAC= is a text string indicating that the precalculated fingerprint follows 

 

12345678 is the Hex ASCII representation of the most significant 4 bytes of the 
MAC value of the SHA1 result for the whole certificate file, precalculated and 
applied by the securing utility prior to download. 

Note:  

The first line of the file must end with a carriage return and line feed. The second 

line is considered to begin at the first character immediately after the first carriage return 
and line feed characters of the file.
