## Constants
```v
const size = 16
```

The size of an MD5 checksum in bytes.

[[Return to contents]](#Contents)

```v
const block_size = 64
```

The blocksize of MD5 in bytes.

[[Return to contents]](#Contents)

## hexhash
```v
fn hexhash(s string) string
```

hexhash returns a hexadecimal MD5 hash sum `string` of `s`.

Example
```v

assert md5.hexhash('V') == '5206560a306a2e085a437fd258eb57ce'

```

[[Return to contents]](#Contents)

## new
```v
fn new() &Digest
```

new returns a new Digest (implementing hash.Hash) computing the MD5 checksum.

[[Return to contents]](#Contents)

## sum
```v
fn sum(data []u8) []u8
```

sum returns the MD5 checksum of the data.

[[Return to contents]](#Contents)

## Digest
## free
```v
fn (mut d Digest) free()
```

free the resources taken by the Digest `d`

[[Return to contents]](#Contents)

## reset
```v
fn (mut d Digest) reset()
```

reset the state of the Digest `d`

[[Return to contents]](#Contents)

## write
```v
fn (mut d Digest) write(p_ []u8) !int
```

write writes the contents of `p_` to the internal hash representation.

[[Return to contents]](#Contents)

## sum
```v
fn (d &Digest) sum(b_in []u8) []u8
```

sum returns the md5 sum of the bytes in `b_in`.

[[Return to contents]](#Contents)

## size
```v
fn (d &Digest) size() int
```

size returns the size of the checksum in bytes.

[[Return to contents]](#Contents)

## block_size
```v
fn (d &Digest) block_size() int
```

block_size returns the block size of the checksum in bytes.
