```
 final Boolean equal(Integer b, Integer c)
```
    Constant-time byte comparison.
    
    Parameters:
    
    b - a byte, represented as an int
    
    c - a byte, represented as an int
  - equal
```
 final Boolean equal(Boolean b, Integer c)
```
  - equal
```
 final Boolean equal(ByteArray b, ByteArray c)
```
    Constant-time ByteArray comparison.
    Fails fast if the lengths differ.
    
    Parameters:
    
    b - a ByteArray
    
    c - a ByteArray
  - isNegative
```
 final Boolean isNegative(Integer b)
```
    Constant-time determine if byte is negative.
    
    Parameters:
    
    b - the byte to check, represented as an int.
  - bit
```
 final Integer bit(ByteArray h, Integer i)
```
    Get the i'th bit of a byte array.
    
    Parameters:
    
    h - the ByteArray.
    
    i - the bit index.
