Checking the key password with FirmaSAT

To check if a password is correct for your key file, use the KEYCHECK command. Pass the filenames of your private key file and the associated certificate file together with the password. The general syntax is 
FirmaSAT KEYCHECK -k <keyfile> -p <password> <certorxmlfile>
  1. If the password is correct (and the key and cert match), you will get "OK": 
    > FirmaSAT KEYCHECK -k CSD01_AAA010101AAA.key -p 12345678a CSD01_AAA010101AAA.cer
OK
  2. If the password is wrong, you will get error code -15 (DECRYPT_ERROR): 
    > FirmaSAT KEYCHECK -k CSD01_AAA010101AAA.key -p WRONG CSD01_AAA010101AAA.cer
Error code -15: Decryption error/De error de descifrado (DECRYPT_ERROR):
Cannot read private key/No se puede leer la clave privada
  3. If the the password is correct, but the key and certificate are not matched, you will get error code -21 (NO_MATCH_ERROR): 
    > FirmaSAT KEYCHECK -k CSD01_AAA010101AAA.key -p 12345678a CSD02_AAA010101AAA.cer
Error code -21: Match not found/No se pudo encontrar datos coincidente (NO_MATCH_ERROR):
