| 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. |
