AS2805
AS2805 is the Australian standard for financial messaging. It is near-exclusively used in Australia for the operation of card-based financial transactions among banks, automatic teller machines and EFTPOS devices. Financial messages described by this standard are closely related to ISO 8583, but pre-dates it by two years (1985 vs 1987).
AS2805 functionality provided by CCALC handles Terminal Keys Set generation, PIN Block translation, plus MAC and OWF generation.
Generate Terminal Key Set
Generates set of terminal keys like a Terminal PIN Key (TPK), Terminal Authentication Key Receive (TAKr), Terminal Authentication Key Send (TAKs), Terminal Encryption Key Receive (TEKr) and Terminal Encryption Key Send (TEKs) and return each key encrypted under a variant of a Terminal Master Key (TMK) or KMA and the appropriate LMK pair. CCALC generates a key check value (KCV) for every output key.
KEK Flag specifies what key is used 1 = KEK1, 2 = KEK2, 3 = TEKr.
Key Encryption Key receive (KEKr) has to be always provided in hexadecimal digits (0-9 | A-F) and key length allowed is 32. The key is encrypted under the appropriate variant of LMK pair 14-15.
Key Scheme KEK says what Key Scheme will be used for encrypting keys under KEKr.
Key Scheme LMK says what Key Scheme will be used for encrypting keys under LMK.
KCV Type sets the length of the key check value (1 = KCV 6H )

OWF
The One-way Function (OWF) is a backbone of AS2805 and is used in majority of previous key generation functions. CCALC implementation complies with the AS2805.5.4 standard as it is described below.
- Let K be a DES key and let D be a data block, of arbitrary length, n bits.
- If n is not a multiple of 64 then append a single binary ‘1’ followed by as many binary zeros as necessary to make the data a multiple of 64 bits (possibly none).
- Let D* denote the padded data.
Key (TAK) has to be always provided in hexadecimal digits (0-9 | A-F) and key length allowed is 32. The key is in its plain form (unencrypted).

DUKPT
DUKPT (ISO 9797)
DUKPT panels consists of tabs following ISO-9797 – IPEK derivation, PEK derivation, PIN encryption and MAC encryption. Method described in ISO-9797 uses Initial Pin Encryption Key (PEK) and Pin Encryption Key (PEK) to encrypt PIN block encryption with unique key per transaction as well as using variant of this key for MAC generation on transaction data provided.
PEK Derivation
IPEK and PEK derivation functions are the first options available. These require Base Derivation Key (BDK) and Key Serial Number (KSN), or IPEK & KSN for PEK derivation, as input parameters. BKD and IPEK keys are expected to be entered in its hexadecimal form and needs to be double length. The KSN has hexa-decimal digits (0-9 | A-F) and input size has to be 20 characters.

DUKPT PIN
DUKPT PIN screen allows PIN block encryption/decoding with a PEK key. Input values are similar to previous screens, just note that entered PEK will be XOR-ed with the value of 00000000000000FF 00000000000000FF (see ANSI X9.24-2004 Appendix A, A.5, page 42) as part of the processing. So there is no need to do that operation in advance (it would exactly negate the previous change).

DUKPT MAC
DUKPT MAC screen takes BDK, KSN and Data fields and outputs ANSI X9.24-2004 MAC with filling option 1. All input fields are expected to be in a hexadecimal format with their appropriate lengths (single/double/triple DEA). Note that the data field size is limited to 8120 characters. The 3DES switch serves to indicate whether the last cryptographic operation applied on hashing value should should be single or triple DES (default).
Entered PEK value will be XOR-ed with the value of 000000000000FF00 000000000000FF00 (see ANSI X9.24-2004 Appendix A, A.5, page 42) as part of the processing.

TDES CBC-MAC
TDES CBC-MAC – A cipher block chaining message authentication code (CBC-MAC) is a technique for constructing a message authentication code from a block cipher. The message is encrypted with some block cipher algorithm in CBC mode to create a chain of blocks such that each block depends on the proper encryption of the previous block. This interdependence ensures that a change to any of the plaintext bits will cause the final encrypted block to change in a way that cannot be predicted or counteracted without knowing the key to the block cipher.

HMAC
In cryptography, an HMAC (sometimes expanded as either keyed-hash message authentication code or hash-based message authentication code) is a specific type of message authentication code (MAC) involving a cryptographic hash function and a secret cryptographic key. As with any MAC, it may be used to simultaneously verify both the data integrity and the authenticity of a message.
HMAC can be used with any iterative cryptographic hash function, e.g., MD5, SHA-1, in combination with a secret shared key.
The cryptographic strength of HMAC depends on the properties of the underlying hash function.

CMAC
CMAC (Cipher-based Message Authentication Code) is a block cipher-based message authentication code algorithm. It may be used to provide assurance of the authenticity and, hence, the integrity of binary data. This mode of operation fixes security deficiencies of CBC-MAC (CBC-MAC is secure only for fixed-length messages).

PIN Offset (IBM 3624 Method)
Offset
To allow the customer to select his own PIN, a PIN offset is used by the IBM 3624 PIN generation algorithm to relate the customer-selected PIN to the generated PIN.
The PIN offset generation algorithm requires two parameters in addition to those used in the 3624 PIN generation algorithm. They are a customer-selected PIN and a 4-bit PIN check length. The length of the customer-selected PIN is equal to the assigned-PIN length.
The offset data value is the result of subtracting (modulo 10) the leftmost n digits of the intermediate PIN from the customer-selected PIN.

PIN PVV Calculator
The VISA method generates a PIN verification value (PVV). Similar to the offset value, it can be stored on the card’s track data, or in a database at the card issuer. This is called the reference PVV.
The VISA method takes the rightmost eleven digits of the PAN excluding the checksum value, a PIN validation key index (PVKI, chosen from one to six) and the required PIN value to make a 64 bit number, the PVKI selects a validation key (PVK, of 128 bits) to encrypt this number. From this encrypted value, the PVV is found.
To validate the PIN, the issuing bank calculates a PVV value from the entered PIN and PAN and compares this value to the reference PVV. If the reference PVV and the calculated PVV match, the correct PIN was entered.
Unlike the IBM method, the VISA method doesn’t derive a PIN. The PVV value is used to confirm the PIN entered at the terminal, was also used to generate the reference PVV. The PIN used to generate a PVV can be randomly generated or user selected or even derived using the IBM method.
This algorithm generates a 4-digit PVV. Inputs are Pin Derivation Key, PAN, PIN and PIN Verification Key Indicator (PVKI). The assigned PVV length parameter is hardcoded = 4.
