SecureRandom.base64 generates a random base64 string.
The argument n specifies the length, in bytes, of the random number to be generated. The length of the result string is about 4/3 of n.
If n is not specified or is nil, 16 is assumed. It may be larger in future.
The result may contain A-Z, a-z, 0-9, “+”, “/” and “=”.

If secure random number generator is not available, NotImplementedError is raised.
See RFC 3548 for the definition of base64.
