Typedef Documentation

BLOCK_CIPHER_CTR_CALLBACK

using BLOCK_CIPHER_CTR_CALLBACK = Delegate<void(Int block, Int blockSize, UChar* nonce)>

param[in] block The block number. param[in] blockSize The size in bytes. param[in] userData User data that was originally passed to the Encrypt and Decrypt function. param[out] nonce A buffer that is filled with the Nonce data. You may only write blockSize bytes.

Enumeration Type Documentation

BLOCK_CIPHER_MODE

enum BLOCK_CIPHER_MODE : UInt64

strong

Block cipher modes. See documentation of the encryption method for details.

Enumerator
ECB	Electronic codebook.
CBC	Cipher-block chaining.
PCBC	Propagating cipher-block chaining.
CFB	Cipher feedback.
OFB	Output feedback.
CTR	Counter.
KEEP_STATE	for CBC, PCBC, CFB, OFB: Store the current state in the instance. Otherwise the next Encrypt call will use the original initialization vector.

Function Documentation

MAXON_ENUM_FLAGS()

enum maxon::BLOCK_CIPHER_MODE UInt64 maxon::MAXON_ENUM_FLAGS

(

BLOCK_CIPHER_MODE

)

GetHashString()

Result<String> maxon::GetHashString

(

const BaseArray< UChar > &

hashValue

)

Returns the hash value as a hexadecimal string. The length of the value depends on the algorithm.

Parameters

[in]

hashValue

The input (byte) values.

Returns

The hexadecimal string.

GetPasswordHash() [1/2]

Result<String> maxon::GetPasswordHash	(	const String &	password,
		const StreamConversionFactory &	hashClass,
		const DataDictionary &	settings = DataDictionary()
	)

Returns the hash value string of a password.

Parameters

[in]	password	The input password.
[in]	hashClass	The algorithm to use, e.g. StreamConversions::HashMD5()
[in]	settings	Settings for the hash algorithm which will be passed to the Init() function.

Returns

The hash value string.

GetPasswordHash() [2/2]

Result<String> maxon::GetPasswordHash	(	const BaseArray< Char > &	password,
		const StreamConversionFactory &	hashClass,
		const DataDictionary &	settings = DataDictionary()
	)

HashPasswordWithSalt()

Result<Tuple<String, String> > maxon::HashPasswordWithSalt	(	const String &	password,
		const StreamConversionFactory &	hashClass = StreamConversions::HashSHA256()
	)

HashPasswdWithSalt creates a unique salt string and hashes the password together with the string hash(salt + password). To verify a password you need to store the salt and call "String hashedPasswd = GetPasswordHash(passwordSalt + passwd, StreamConversions::HashSHA256())" to get the hashed passwd.

Parameters

[in]	password	Password to hash.
[in]	hashClass	HashClass to use.

Returns

Tuple<salt, passwordhash> if no error occurred.

AddConversionTestSetting()

Result<void> maxon::AddConversionTestSetting	(	MAXON_SOURCE_LOCATION_DECLARATION	,
		BaseArray< DataDictionary > &	resultArray,
		const Id &	encoderId,
		const Id &	decoderId,
		Int	blockSizeBits,
		const void *	key1,
		Int	key1BitSize,
		const void *	key2 = nullptr,
		Int	key2BitSize = 0,
		UInt64	flags = 0,
		BLOCK_CIPHER_CTR_CALLBACK &&	callback = BLOCK_CIPHER_CTR_CALLBACK(),
		const Char *	srcData = nullptr,
		const Char *	compareData = nullptr
	)

Helper function to add crypto tests.
