Determines the equality of two byte sequences in an amount of time that depends on the length of the sequences, but not their values.
public:
static bool FixedTimeEquals(ReadOnlySpan<System::Byte> left, ReadOnlySpan<System::Byte> right);public static bool FixedTimeEquals(ReadOnlySpan<byte> left, ReadOnlySpan<byte> right);static member FixedTimeEquals : ReadOnlySpan<byte> * ReadOnlySpan<byte> -> boolPublic Shared Function FixedTimeEquals (left As ReadOnlySpan(Of Byte), right As ReadOnlySpan(Of Byte)) As BooleanParameters
- left
- ReadOnlySpan<Byte>
The first buffer to compare.
- right
- ReadOnlySpan<Byte>
The second buffer to compare.
Returns
true if left and right have the same values for Length and the same contents; otherwise, false.
Remarks
This method compares the contents from two buffers for equality in a way that doesn't leak timing information, making it ideal for use within cryptographic routines.
This method will short-circuit and return false only if left and right have different lengths.
Fixed-time behavior is guaranteed in all other cases, including when left and right reference the same address.
