    Class
    Description
    Elligator2MapToCurve
    Implements the Elligator 2 Map to curve according to section 6.7.1 of RFC 9380 This is the straight-line implementation optimized for Montgomery curves as defined in section F.3.
    GenericSqrtRatioCalculator
    Generic implementation of the sqrt_ratio(u, v) operation defined in RFC 9380.
    MontgomeryCurveProcessor
    Curve processor for Montgomery curves of the form B * y^2 = x^3 + A * x^2 + x Internally we treat this as a long Weierstrass curve y^2 = x^3 + a2 * x^2 + a4 * x + a6 with a2 = A / B, a4 = 1 / B, a6 = 0.
    NistCurveProcessor
    Curve processor for NIST curves (P-256, P-384, P-521) where the cofactor is 1.
    SimplifiedShallueVanDeWoestijneMapToCurve
    Implements the Simplified Shallue van de Woestijne Map to curve according to section 6.6.2 of RFC 9380 This is the straight-line implementation optimized for Weierstrass curves as defined in section F.2.
    SqrtRatio
    The result of a sqrt_ratio calculation
    XmdMessageExpansion
    XmdMessageExpansion is an implementation of the MessageExpansion interface, used to expand a given message to a specified length in bytes while following cryptographic domain separation principles.
