How to Convert a Size-Constrained Byte Array to a String in Go?

Converting a Size-Constrained Byte Array to String in Go

When working with byte arrays in Go, it's possible to encounter situations where the array is size-constrained, for instance, when using the md5.Sum function. In this case, attempting to directly assign the byte array to a string via string(b) may result in a type conversion error.

To overcome this error, you can exploit the fact that a byte array can be treated as a byte slice. By appending [:] to the byte array, you can effectively create a slice that encompasses the entire array:

var b [16]byte
b = md5.Sum(data)
pass := string(b[:])

By doing so, the b array is effectively treated as a slice, enabling the conversion to a string without encountering type conversion issues.
