Class Detail

Mifare(card)

Create a Mifare card object

Parameters:
{card} card: the card object

Field Detail

<static> Mifare.KEY_A

Identifier for Key A

<static> Mifare.KEY_B

Identifier for Key B

<static> Mifare.PUBLICKEYS

Mifare Public Key Values

Method Detail

{boolean} authenticate(block, keytype, keyid)

Perform authentication procedure using General Authenticate command as defined in PCSC Part 3, chapter 3.2.2.1.6

Parameters:
{Number} block: the block to authenticate against
{Number} keytype: must be either Mifare.KEY_A or Mifare.KEY_B
{Number} keyid: the key id of the key in the reader

Returns:: true if authentication successfull

<static> {Number} Mifare.crc8(data)

Calculate CRC-8 checksum Based on code from nfc-tools.

Parameters:
{ByteString} data: the data to calculate the checksum for

Returns:: the crc checksum

{ByteString} getUID()

Read UID using Get Data command as defined in PCSC Part 3, chapter 3.2.2.1.3

FEIG readers require Le='04' to automatically switch to Mifare if the card supports both T=CL and Mifare.

Returns:: the 4 byte UID

loadKey(keyid, key)

Load key value into reader using Load Key command as defined in PCSC Part 3, chapter 3.2.2.1.4

The ACR 122U contactless reader supports key ids 0x00 and 0x01

The Omnikey cardman 5321 reader supports key ids 0x00 to 0x1F

The ACR 122U contactless reader supports key ids 0x00 and 0x01

The method supports the SCM SDI010 contactless reader which uses a proprietary LOAD KEY APDU with preset key identifier 0x60 and 0x61. This command is activated if keyid is 0x60 or 0x61.

Parameters:
{Number} keyid: the key identifier under which the key should be refered to in the reader
{ByteString} key: the 6 byte key value

newSector(no)

Create a sector object bound to the current Mifare instance

Parameters:
{Number} no: the sector number

{ByteString} readBlock(block)

Read a block using the Read Binary command as defined in PCSC Part 3, chapter 3.2.2.1.8

Parameters:
{Number} block: the block to read, starting at 0 for the first block in the first sector.

Returns:: the 16 byte block content read from the card

updateBlock(block, data)

Update a block using the Update Binary command as defined in PCSC Part 3, chapter 3.2.2.1.9

Parameters:
{Number} block: the block to read, starting at 0 for the first block in the first sector.
{ByteString} data: the 16 bytes of the data block to write
