Activate Transaction Command Frame Data Format
Data Item
Length (bytes)
Description
Timeout
1
Time in seconds that the reader waits for a card to be presented before
timing out and returning an Error response. The reader will continue to poll
for this amount of time if no card is found.
Note that if a card is found, the transaction may not complete within the
timeout period.
This field must be present in the Activate command.

Hash Algorithm
1
The only algorithm supported is SHA-1. The value is set to 01h
1
Public Key
Algorithm
1
The encryption algorithm in which this key is used. Currently support
only one type: RSA. The value is set to 01h
3-22
Checksum/Hash
20
Checksum which is calculated using SHA-1 over the following fields:
RID & KeyIndex & Modulus & Exponent
where the exponent is either one byte or 3 bytes (although we store it
in a 4-byte field)
23-26
Public Key
Exponent
4
Actually, the real length of the exponent is either one byte or 3 bytes. It
can have two values: 3, or 65537.
27-28
Modulus Length
2
Indicates the length of the next field, MSB followed by LSB.
29-n
Modulus
Variable
This is the modulus field of the public key. Its length is specified in the
field above.
