Constructors

Argon2

Initializes a new instance of the Argon2 class.

Properties

LaneBlockCount	Gets the number of memory blocks per lane. SegmentBlockCount * SyncPointCount.
Memory	Gets the MemoryBlockCount blocks.
MemoryBlockCount	Gets the number of memory blocks, (Lanes*LaneBlockCount).
SegmentBlockCount	Gets the number of memory blocks per segment. This value gets derived from the memory cost. The memory cost value is a request for that number of blocks. If that request is less than (2 * SyncPointCount) times the number of lanes requested, it is first bumped up to that amount. Then, it may be reduced to fit on a SyncPointCount times the number of lanes requested boundary.

Methods

Dispose	Zero sensitive memories and dispose of resources.
Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
FixedTimeEquals	Compare two ZeroedBuffers without leaking timing information.
GetHashCode	Serves as the default hash function. (Inherited from Object)
GetType	Gets the Type of the current instance. (Inherited from Object)
Hash	Perform the hash.
Hash(Argon2Config)	Hash the given password to an Argon2 hash string.
Hash(String, Int32, Int32, Int32, Argon2Type, Int32)	Hash the given password to an Argon2 hash string.
Hash(Byte, Byte, Int32, Int32, Int32, Argon2Type, Int32)	Hash the given password to an Argon2 hash string.
Hash(String, String, Int32, Int32, Int32, Argon2Type, Int32)	Hash the given password to an Argon2 hash string.
ToString	Returns a string that represents the current object. (Inherited from Object)
Verify(String, Argon2Config)	Verify the given Argon2 hash as being that of the given password.
Verify(String, Byte)	Verify the given Argon2 hash as being that of the given password.
Verify(String, String)	Verify the given Argon2 hash as being that of the given password.
Verify(String, Byte, Byte)	Verify the given Argon2 hash as being that of the given password.
Verify(String, Byte, Int32)	Verify the given Argon2 hash as being that of the given password.
Verify(String, String, Int32)	Verify the given Argon2 hash as being that of the given password.
Verify(String, String, String)	Verify the given Argon2 hash as being that of the given password.
Verify(String, Byte, Byte, Int32)	Verify the given Argon2 hash as being that of the given password.
Verify(String, String, String, Int32)	Verify the given Argon2 hash as being that of the given password.

Fields

BlockSize	The Argon2 block size in bytes.
CsharpMaxBlocksPerArray	C# has a limit of 0X7FEFFFFF elements per array (0x7FFFFFC7 per byte array). The blocks are 1024 bytes long, the elements are 8 bytes (ulong). This gives 0X7FEFFFFF / 128 blocks per C# array.
PrehashDigestLength	The number of bytes hashed in initializing Argon2.
PrehashSeedLength	Bytes required in the buffer passed into the FillFirstBlocks(Byte) method.
QwordsInBlock	The number of 8-byte words in an Argon2 block.
SyncPointCount	Number of synchronization points between lanes per pass.
