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.
A security-sensitive bug was discovered by Open Source Developer Erik Sundell of Sundell Open Source Consulting AB. The functions RandomAlphaNumeric(int) and CryptoRandomAlphaNumeric(int) are not as random as they should be.
A security-sensitive bug was discovered by Open Source Developer Erik Sundell of Sundell Open Source Consulting AB. The functions RandomAlphaNumeric(int) and CryptoRandomAlphaNumeric(int) are not as random as they should be. Small values of int in the functions above will return a smaller subset of results than they should. For example, RandomAlphaNumeric(1) will always return a digit in the 0-9 range, while RandomAlphaNumeric(4) will return around ~7 million of the ~13M …
