		iqr_XMSSPrivateKey **	private_key,
		iqr_XMSSPrivateKeyState **	state
	)

Generate an XMSS private/public key pair.

This can take a significant amount of time, especially when creating a height 20 tree (using IQR_XMSS_HEIGHT_20).

The iqr_XMSSCreateKeyPair() function calls the watchdog callback (see iqr_watchdog.h).

Note: You must register a SHA2-256 implementation by calling iqr_HashRegisterCallbacks() before using the XMSS API.

The rng must be initialized before being passed to iqr_XMSSCreateKeyPair().

*public_key, *private_key, and state must be set to NULL before calling iqr_XMSSCreateKeyPair().

Parameters

[in]	params	The key parameters to use.
[in]	rng	A seeded random number generator.
[out]	public_key	The resulting `iqr_XMSSPublicKey` object.
[out]	private_key	The resulting `iqr_XMSSPrivateKey` object.
[out]	state	The resulting `iqr_XMSSPrivateKeyState` object.

Returns: IQR_OK on success, or a value from iqr_retval.h when an error occurs.

		const iqr_XMSSTreeStrategy *	strategy,
		iqr_XMSSHeight	h,
		iqr_XMSSParams **	params
	)

Create an XMSS Parameters object that encapsulates domain parameters.

It's up to the user to manage domain parameters; the parameter data is not exposed in stored keys or signatures.

Note: You must register a SHA2-256 implementation by calling iqr_HashRegisterCallbacks() before using the XMSS API.

*params must be set to NULL before calling iqr_XMSSCreateParams().

Parameters

[in]	ctx	A Context object.
[in]	strategy	The tree strategy.
[in]	h	The `iqr_XMSSHeight`.

IQR_API_UNENFORCED_RETURN iqr_retval iqr_XMSSDestroyParams ( iqr_XMSSParams ** params )

Clear and deallocate an XMSS key parameters object.

params will be set to NULL before returning.

All internal iqr_XMSSParams buffers are cleared and deallocated during the call to iqr_XMSSDestroyParams(). The iqr_XMSSParams object does not store any cryptographic material.

Parameters

[in,out] params The iqr_XMSSParams instance to destroy.

Returns: IQR_OK on success, or a value from iqr_retval.h when an error occurs.

◆ iqr_XMSSDestroyPrivateKey()

Clear and deallocate an XMSS private key.

*private_key will be set to NULL prior to returning.

The private key's data is cleared before its internal buffers are deallocated.

Parameters

[in,out] private_key The iqr_XMSSPrivateKey object to destroy.

Returns: IQR_OK on success, or a value from iqr_retval.h when an error occurs.

◆ iqr_XMSSDestroyPublicKey()

*public_key will be set to NULL prior to returning.

Parameters

[in,out] public_key The iqr_XMSSPublicKey object to destroy.

Returns: IQR_OK on success, or a value from iqr_retval.h when an error occurs.

		iqr_XMSSPrivateKeyState *	state,
		uint32_t	num_sigs,
		iqr_XMSSPrivateKeyState **	detached_state
	)

Detaches a subset of signatures from state into a new state object.

This function can be used to split a state into two distinct, non-overlapping state objects. This operation effectively "reserves" a number of signatures from state and places them into a new distinct object, detached_state. Both state objects must be used with the same private key to generate signatures.

This operation is useful for disaster recovery, whereby a small section of the state is detached and used for signing while the rest of the state is persisted in non-volatile memory. Or, this feature can be used to aid in the distribution of a state and key pair to multiple machines, where each machine is given a distinct state.

The detached_state will have a reduced number of maximum signatures once this function returns. Use iqr_XMSSGetSignatureCount() to obtain the number of available signatures. Use iqr_XMSSGetStateSize() to obtain the state sizes prior to exporting.

In the unlikely case that an error occurs while state is being updated, the state will become unusable. This function and any subsequent function calls will return IQR_ESTATECORRUPTED.

Parameters

[in]	private_key	The private key.
[in,out]	state	The original state to be split.
[in]	num_sigs	The number of signatures to split off.
[out]	detached_state	A new state object containing num_sigs signatures.

Returns: IQR_OK on success, or a value from iqr_retval.h when an error occurs.

		iqr_XMSSPrivateKeyState *	state,
		uint8_t *	sig,
		size_t	sig_size
	)

Sign a message using an XMSS private key.

As signatures are generated, the state can run out of signing keys. In that case, IQR_EKEYDEPLETED is returned and the key can no longer be used for signing. Use iqr_XMSSGetSignatureCount() to check to total number of signatures and the number of signatures remaining.

Each time this function is called, the state is advanced to the next usable state. You must store this new state in non-volatile memory prior to releasing the signature. Alternatively, use iqr_XMSSDetachState() to work with smaller states that can be lost without catastrophe. For more details, refer to the Developer's Guide (online: Toolkit edition, or Signature edition).

In the unlikely case that an error occurs while state is being updated, the state will become unusable. This function and any subsequent function calls will return IQR_ESTATECORRUPTED.

Warning: Restarting from a previous state makes XMSS insecure.

If the message is a digest of a hash function it must be 48 bytes or longer to be quantum-safe.

Note: You must register a SHA2-256 implementation by calling iqr_HashRegisterCallbacks() before using the XMSS API.

The rng must be initialized before being passed to iqr_XMSSSign().

All internal buffers are cleared and deallocated before the call to iqr_XMSSSign() returns.

Parameters

[in]	private_key	The private key.
[in]	rng	A seeded random number generator.
[in]	message	The message to be signed.
[in]	message_size	The size of message in bytes.
[in,out]	state	The state object.
[out]	sig	The buffer receiving the resulting signature.
[in]	sig_size	The size of sig in bytes. Must be exactly the size returned by `iqr_XMSSGetSignatureSize()`.

Returns: IQR_OK on success, or a value from iqr_retval.h when an error occurs.

◆ iqr_XMSSVerify()

IQR_API iqr_retval iqr_XMSSVerify	(	const iqr_XMSSPublicKey *	public_key,
		const uint8_t *	message,
		size_t	message_size,
		const uint8_t *	sig,
		size_t	sig_size
	)

Verify the signature of a message using an XMSS public key.

Note: If the message is a digest of a hash function it should be 48 bytes or longer to be quantum-safe.; You must register a SHA2-256 implementation by calling iqr_HashRegisterCallbacks() before using the XMSS API.

All internal buffers are cleared and deallocated before the call to iqr_XMSSVerify() returns.

Parameters

[in]	public_key	The public key.
[in]	message	The message to verify.
[in]	message_size	The size of message in bytes.
[in]	sig	The signature to verify.
[in]	sig_size	The size of sig in bytes. Must be exactly the size returned by `iqr_XMSSGetSignatureSize()`.

Variable Documentation

◆ IQR_XMSS_BDS_STRATEGY

IQR_EXTERN const iqr_XMSSTreeStrategy IQR_XMSS_BDS_STRATEGY

Tree strategies offer a trade-off between CPU utilization and memory usage during signing. Choosing the correct strategy is highly dependent on the hardware restrictions of the target platform.

Please see the Developer's Guide (online: Toolkit edition, or Signature edition) for state size requirements. Implements the BDS algorithm as proposed in the Merkle Tree Traversal Revisited Whitepaper. This strategy features minimal memory requirements at the cost of recomputing parts of the Merkle tree. This option is ideal for memory constrained devices with a fast CPU to handle recomputation. This is an excellent choice for embedded platforms, such as Hardware Security Modules.

◆ IQR_XMSS_FULL_STRATEGY

IQR_EXTERN const iqr_XMSSTreeStrategy IQR_XMSS_FULL_STRATEGY

Implements a full Merkle tree in memory. This strategy offers the least CPU utilization at the cost of using memory. This option is ideal for servers with large amounts of memory that need to generate signatures frequently. For larger tree heights, this strategy requires up to 2GB of memory to store the state.

◆ IQR_XMSS_VERIFY_ONLY_STRATEGY

IQR_EXTERN const iqr_XMSSTreeStrategy IQR_XMSS_VERIFY_ONLY_STRATEGY

This strategy is only used to verify signatures; it cannot be used to create or import private keys nor can it be used to create signatures. This option is ideal for a client that only needs to verify signatures.

Detailed Description

ISARA Radiate Security Solution Suite's eXtended Merkle Signature Scheme.

XMSS is defined by the RFC: XMSS: eXtended Merkle Signature Scheme by Huelsing et al.

This header contains the functions and parameters necessary to create and verify an XMSS signature. The two main functions are iqr_XMSSSign() and iqr_XMSSVerify(). The rest of the functions let you create and manipulate XMSS keys.

This scheme has some fundamental differences from traditional signature schemes such as RSA or ECDSA. In particular, you'll need to manage the state used by iqr_XMSSSign() carefully. For more details, refer to the Developer's Guide (online: Toolkit edition, or Signature edition).

Note: As specified above, the state is managed by the user. This differs from the IETF specification, where the state is stored and updated within the private key as an index.
