HMAC-SHA-1

newSHA1Key :: IO AuthenticationKey Source #

Create an new random key to be used with the SHA-1 functions

Since: 3.0.0.0

hotpSHA1 Source #

Arguments

:: AuthenticationKey	Shared secret
-> Word64	Counter value
-> Digits	Number of digits in a password. MUST be 6 digits at a minimum, and possibly 7 and 8 digits.
-> OTP	HOTP

Compute HMAC-Based One-Time Password using secret key and counter value.

Since: 3.0.0.0

hotpSHA1Check Source #

Arguments

:: AuthenticationKey	Shared secret
-> (Word64, Word64)	Valid counter range, before and after ideal
-> Word64	Ideal (expected) counter value
-> Digits	Number of digits provided
-> Text	Digits entered by user
-> Bool	True if password is valid

Check presented password against a valid range.

Since: 3.0.0.0
