HmacSha1 Field

Namespace: Yubico.YubiKey.Otp Assembly: Yubico.YubiKey.dll

The HMAC-SHA1 mode creates a HMAC on a 0-64 byte (0-512 bits) data block using a 20 byte (160 bits) fixed key. As all input to the challenge response algorithm is static, the response is deterministic in this mode. That is, if the same challenge is issued repeatedly, the response will be identical each time.
