# Checksum160

Represents a 160 bit checksum (20 bytes)

# Constructor

constructor(
  data: u8[] | null = null
)

data - byte array for initial value of checksum

```
static function pack(): u8[]
```
Returns serialized data bytes in the checksum
```
static function unpack(data: u8[]): usize
```
Tries to place the first 20 bytes from data into the checksum. Returns how many bytes were unpacked from data.
```
static function toString(): string
```
Prints the hex representation of the bytes in the checksum

static function eq(a: Checksum160, b: Checksum160): bool

Checks that the two checksum bytes are equal

static function neq(a: Checksum160, b: Checksum160): bool

Checks that the checksum bytes are not equal
