Class BSVShimECPoint ¶

Inherits: Object

Shim Point wrapping BSV::Primitives::Secp256k1::Point.

Attributes¶

group [R] ¶

Returns the value of attribute group.

Public Class Methods¶

from_secp_point(group, secp_point) ¶

Not documented.

Public Instance Methods¶

add(other) ¶

Not documented.

infinity?() ¶

• @return [Boolean]

initialize(group, bn = nil) ¶

• @return [BSVShimECPoint] a new instance of BSVShimECPoint

mul(*args) ¶

Scalar multiplication: self * scalar (constant-time, Montgomery ladder).

Matches OpenSSL convention where EC_POINT_mul is always constant-time. Safe for both secret and public scalars.

Also supports the multi-scalar form: +mul(bns, points)+ computes bns[0]self + bns[1]points[0] + ... where +bns.length == points.length + 1+. - @overload mul - @overload mul - @return [BSVShimECPoint]

mul_ct(scalar_bn) ¶

Constant-time scalar multiplication (alias for {#mul}).

Retained for backward compatibility and expressiveness. Delegates to {#mul}, which is constant-time by default. - @param scalar_bn [OpenSSL::BN, Integer] the scalar multiplier - @return [BSVShimECPoint]

mul_vt(scalar_bn) ¶

Variable-time scalar multiplication (wNAF).

Faster than {#mul} but leaks timing information about the scalar. Use only for public scalars (e.g. signature verification). - @param scalar_bn [OpenSSL::BN, Integer] the public scalar multiplier - @return [BSVShimECPoint]

set_to_infinity!() ¶
