Base58Check is a C# implementation of Base58 Checked Encoding, based on a public domain Gist by @CodesInChaos.
In short, Base58 is a encoding algorithm similar to Base64, removing certain characters that cause issues with URLs, and cause confusion because of how similar they look in certain fonts. Base58Check adds a 4 byte checksum to validate that the data hasn't been altered in transmission. This checksum isn't suitable to perform cryptographic validation, but is does detect accidental corruption.

Base58Check.Encode(byte[])- Encodes data with a 4-byte checksumBase58Check.Decode(string)- Decodes data in Base58Check format (with 4 byte checksum)Base58Check.EncodePlain(byte[])- Encodes data in plain Base58, without any checksumBase58Check.DecodePlain(string)- Decodes data in plain Base58, without any checksum
The Encode* methods both expect a byte array of arbitrary length; as the entire payload to encode must be loaded into memory, an OutOfMemoryException may be thrown for large payloads. The Decode* methods will throw a FormatException if the string passed in isn't in a valid Base58 format; the Decode method will also throw the FormatException if the checksum verification fails.
