Operations. Fixed Time Equals Method

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> -> bool
Public Shared Function FixedTimeEquals (left As ReadOnlySpan(Of Byte), right As ReadOnlySpan(Of Byte)) As Boolean
right have the same values for Length and the same contents; otherwise,
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
right have different lengths.
Fixed-time behavior is guaranteed in all other cases, including when
right reference the same address.
