ICLRStrongName::StrongNameGetPublicKey Method

Gets the public key from a public/private key pair. The key pair can be supplied either as a key container name within a cryptographic service provider (CSP) or as a raw collection of bytes.

HRESULT StrongNameGetPublicKey ( 
    [in]  LPCWSTR   szKeyContainer,
    [in]  BYTE      *pbKeyBlob,
    [in]  ULONG     cbKeyBlob,
    [out] BYTE      **ppbPublicKeyBlob,
    [out] ULONG     *pcbPublicKeyBlob
);

szKeyContainer

[in] The name of the key container that contains the public/private key pair. If pbKeyBlob is null, szKeyContainer must specify a valid container within the CSP. In this case, the ICLRStrongName::StrongNameGetPublicKey method extracts the public key from the key pair stored in the container.

If pbKeyBlob is not null, the key pair is assumed to be contained in the key binary large object (BLOB).

The keys must be 1024-bit Rivest-Shamir-Adleman (RSA) signing keys. No other types of keys are supported at this time.

pbKeyBlob

[in] A pointer to the public/private key pair. This pair is in the format created by the Win32 CryptExportKey function. If pbKeyBlob is null, the key container specified by szKeyContainer is assumed to contain the key pair.

cbKeyBlob

[in] The size, in bytes, of pbKeyBlob.

ppbPublicKeyBlob

[out] The returned public key BLOB. The ppbPublicKeyBlob parameter is allocated by the common language runtime and returned to the caller. The caller must free the memory by using the ICLRStrongName::StrongNameFreeBuffer method.

pcbPublicKeyBlob

[out] The size of the returned public key BLOB.

S_OK if the method completed successfully; otherwise, an HRESULT value that indicates failure (see Common HRESULT Values for a list).

The public key is contained in a PublicKeyBlob structure.
