GENERATE KEYS

This sample code will generate a set of crypto keys:

     <cfx _pwcardcrypt action="generate"
                       key_length="512">

The returned variables would contain:

     PRIVATE_KEY:  <private key>
     PUBLIC_KEY:   <public key>

VALIDATE SINGLE CARD

This code will validate a single credit card number:

     <cfx_pwcardcrypt action="validate"
                      card_number="4242424242424242"
                      card_expiry_m="10"
                      card_expiry_y="02"
                      card_type="visa">

The returned variable would contain:

     RESULT:  OK

VALIDATE MULTIPLE CARDS

This will validate 4 cards at once:

     <cfx_pwcardcrypt action="validate"
                      card_number="4242,4242,4242,4242"
                      card_expiry_m="10,11,05,06"
                      card_expiry_y="05,04,03,01"
                      card_type="visa,visa,visa,visa">

The result would contain a delimited list of the return values:

     RESULT:  OK,OK,OK,CARD_EXPIRED

ENCRYPT SINGLE CARD

This will encrypt a single credit card number, using a 512bit key. The #public_key# variable should contain the previously generated public key:

     <cfx_pwcardcrypt action="encrypt"
                      card_number="424242"
                      card_expiry_m="10"
                      card_expiry_y="05"
                      card_type="visa"
                      crypt_key="#public_key#"
                      key_length="512">

This would return the following variables:

     RESULT:      OK
     CRYPT_VALUE: <encrypted text>

ENCRYPT MULTIPLE CARDS

This will encrypt 3 card numbers, using a 1024 bit key:

     <cfx_pwcardcrypt action="encrypt"
                      card_number="424242,424242,123456"
                      card_expiry_m="10,11,05"
                      card_expiry_y="05,04,03"
                      card_type="visa,visa,visa"
                      crypt_key="#public_key#"
                      key_length="1024">

The result would contain a delimited list of the return values:

     RESULT:      OK,OK,INVALID_VISA_NUMBER
     CRYPT_VALUE: <encrypted text>,<encrypted text>,INVALID_VISA_NUMBER

DECRYPT SINGLE CARD

The following code will decrypt a single credit card number, using a 512bit key:

     <cfx_pwcardcrypt action="decrypt"
                      card_number="#encrypted_text#"
                      crypt_key="#private_key#"
                      key_length="512">

This would return the following variables:

     RESULT:      OK
     CRYPT_VALUE: <decrypted text>

DECRYPT MULTIPLE CARDS

This code will decrypt 2 card numbers, using a 1024 bit key, and changing the delimiter to a pipe:

     <cfx_pwcardcrypt action="decrypt"
                      card_number="#encrypted_text#|#encrypted_text#"
                      crypt_key="#private_key#"
                      key_length="1024"
                      delimiter="|">

The result would contain a delimited list of the return values:

     RESULT:      OK|OK
     CRYPT_VALUE: <decrypted text>|<decrypted text>

VALIDATE & ENCRYPT SINGLE CARD

The following code will validate & encrypt a single credit card number, using a 512bit key:

     <cfx_pwcardcrypt action="validate_encrypt"
                      card_number="4242424242424242"
                      card_expiry_m="10"
                      card_expiry_y="05"
                      card_type="visa"
                      crypt_key="#public_key#"
                      key_length="512">

This would return the following variables:

     RESULT:      OK
     CRYPT_VALUE: <encrypted text>

VALIDATE & ENCRYPT MULTIPLE CARDS

This code will validate & encrypt 3 card numbers, using a 1024 bit key:

     <cfx_pwcardcrypt action="validate_encrypt"
                      card_number="424242,424242,123456"
                      card_expiry_m="10,12,03"
                      card_expiry_y="04,01,05"
                      card_type="visa,visa,visa"
                      crypt_key="#public_key#"
                      key_length="1024">

The result would contain a delimited list of the return values:

     RESULT:      OK,CARD_EXPIRED,INVALID_VISA_NUMBER
     CRYPT_VALUE: <encrypted text>,CARD_EXPIRED,INVALID_VISA_NUMBER
