Detailed Description

Represents one explicitly trusted RSA-1024 public key for DSi header authentication. Trust is supplied by the caller; constructing this value does not imply that a modulus belongs to Nintendo or any particular publisher.

Constructor & Destructor Documentation

NdsDsiRsaPublicKey()

NdsForge.NdsDsiRsaPublicKey.NdsDsiRsaPublicKey ( ReadOnlySpan< byte > modulus, ReadOnlySpan< byte > exponent )

inline

Copies raw parameters so trust configuration remains stable after caller buffers are reused or cleared.

Parameters

modulus	Exactly 128 bytes forming a 1024-bit modulus.
exponent	Non-empty positive public exponent, commonly 01 00 01.

Member Function Documentation

FromRsa()

NdsDsiRsaPublicKey NdsForge.NdsDsiRsaPublicKey.FromRsa ( RSA rsa )

inlinestatic

Snapshots the public portion of an existing RSA object after enforcing the DSi key size.

Parameters

rsa	RSA instance whose ownership and lifetime remain with the caller.

Returns

An independent immutable public-key value.

Definition at line 33 of file NdsDsiRsaPublicKey.cs.

VerifyHeader()

bool NdsForge.NdsDsiRsaPublicKey.VerifyHeader ( ReadOnlySpan< byte > signedHeader, ReadOnlySpan< byte > signature )

inline

Verifies the format-mandated RSA-SHA1 PKCS#1 v1.5 signature over a finalized header prefix.

Parameters

signedHeader	Exactly 0xE00 bytes from header offset zero.
signature	Exactly 128 on-disk signature bytes.

Returns

true only when the signature matches this caller-trusted key.
