      "value": "Randomly-generated alphanumeric strings contain significantly less entropy than expected. The RandomAlphaNumeric and CryptoRandomAlphaNumeric functions always return strings containing at least one digit from 0 to 9. This significantly reduces the amount of entropy in short strings generated by these functions."

Las funciones RandomAlphaNumeric y CryptoRandomAlphaNumeric siempre devuelven cadenas que contienen al menos un d\u00edgito del 0 al 9. Esto reduce significativamente la cantidad de entrop\u00eda en cadenas cortas generadas por estas funciones."
