Methods

EncodeBytes(Byte[])

Converts a byte array to a Base32 string representation.

public string EncodeBytes(Byte[] bytes)

Parameters

bytes Byte[]
The byte array to convert.

Returns

String
The Base32 string representation of the byte array.

Exceptions

ArgumentNullException
Thrown when parameter is null.

GetBytes(String)
