Declaration
[Pure]
public static ImmutableArray<byte> ParseHexToImmutable(string hex)
Parameters
Type | Name | Description |
---|---|---|
System.String | hex | A System.String which encodes System.Bytes in hexadecimal. Its length must be zero or an even number. It must not be null. |

| Improve this Doc View SourceSatisfies(IReadOnlyList<Byte>, Int64)
Tests if a hash digest is less than the target computed for the given
difficulty
).
Declaration
[Pure]
public static bool Satisfies(IReadOnlyList<byte> hashDigest, long difficulty)
Parameters
Type | Name | Description |
---|---|---|
System.Collections.Generic.IReadOnlyList<System.Byte> | hashDigest | A hash digest to test. |
System.Int64 | difficulty | The difficulty to compute target number. |
Returns
Type | Description |
---|---|
System.Boolean | true only if a digest is less than the target computed for
the given |
TimingSafelyCompare(IReadOnlyList<Byte>, IReadOnlyList<Byte>)
Timing safe comparison of two byte arrays.
Declaration
[Pure]
public static bool TimingSafelyCompare(IReadOnlyList<byte> left, IReadOnlyList<byte> right)
Parameters
Type | Name | Description |
---|---|---|
System.Collections.Generic.IReadOnlyList<System.Byte> | left | A byte array. |
System.Collections.Generic.IReadOnlyList<System.Byte> | right | Another byte array. |
Returns
Type | Description |
---|---|
System.Boolean | true iff two byte arrays have the exactly same contents. |
Remarks
In case of two byte arrays do not have the same length, it tries to keep the timing dependent on the length of the shorter one.
