RsaCheckKey()

BOOLEAN EFIAPI RsaCheckKey

(

IN VOID *

RsaContext

)

Validates key components of RSA context.

Return FALSE to indicate this interface is not supported.

Parameters

[in]

RsaContext

Pointer to RSA context to check.

Return values

FALSE

This interface is not supported.

RsaGenerateKey()

BOOLEAN EFIAPI RsaGenerateKey	(	IN OUT VOID *	RsaContext,
		IN UINTN	ModulusLength,
		IN CONST UINT8 *	PublicExponent,
		IN UINTN	PublicExponentSize
	)

Generates RSA key components.

Return FALSE to indicate this interface is not supported.

Parameters

[in,out]	RsaContext	Pointer to RSA context being set.
[in]	ModulusLength	Length of RSA modulus N in bits.
[in]	PublicExponent	Pointer to RSA public exponent.
[in]	PublicExponentSize	Size of RSA public exponent buffer in bytes.

Return values

FALSE

This interface is not supported.

RsaGetKey()

BOOLEAN EFIAPI RsaGetKey	(	IN OUT VOID *	RsaContext,
		IN RSA_KEY_TAG	KeyTag,
		OUT UINT8 *	BigNumber,
		IN OUT UINTN *	BnSize
	)

Gets the tag-designated RSA key component from the established RSA context.

Return FALSE to indicate this interface is not supported.

Parameters

[in,out]	RsaContext	Pointer to RSA context being set.
[in]	KeyTag	Tag of RSA key component being set.
[out]	BigNumber	Pointer to octet integer buffer.
[in,out]	BnSize	On input, the size of big number buffer in bytes. On output, the size of data returned in big number buffer in bytes.

Return values

FALSE

This interface is not supported.

RsaPkcs1Sign()

BOOLEAN EFIAPI RsaPkcs1Sign	(	IN VOID *	RsaContext,
		IN CONST UINT8 *	MessageHash,
		IN UINTN	HashSize,
		OUT UINT8 *	Signature,
		IN OUT UINTN *	SigSize
	)

Carries out the RSA-SSA signature generation with EMSA-PKCS1-v1_5 encoding scheme.

Return FALSE to indicate this interface is not supported.

Parameters

[in]	RsaContext	Pointer to RSA context for signature generation.
[in]	MessageHash	Pointer to octet message hash to be signed.
[in]	HashSize	Size of the message hash in bytes.
[out]	Signature	Pointer to buffer to receive RSA PKCS1-v1_5 signature.
[in,out]	SigSize	On input, the size of Signature buffer in bytes. On output, the size of data returned in Signature buffer in bytes.

Return values

FALSE

This interface is not supported.
