public class Base58 extends java.lang.Object
Base58 is a way to encode Bitcoin addresses as numbers and letters. Note that this is not the same base58 as used by Flickr, which you may see reference to around the internet.
Satoshi says: why base-58 instead of standard base-64 encoding?
- Don't want 0OIl characters that look the same in some fonts and could be used to create visually identical looking account numbers.
- A string with non-alphanumeric characters is not as easily accepted as an account number.
- E-mail usually won't line-break if there's no punctuation to break at.
- Doubleclicking selects the whole number as one word if it's all alphanumeric.

encode
public static java.lang.String encode(byte[] input)
Encodes the given bytes in base58. No checksum is appended.

doubleDigest
public static byte[] doubleDigest(byte[] input, int offset, int length)
Calculates the SHA-256 hash of the given byte range, and then hashes the resulting hash again. This is standard procedure in Bitcoin. The resulting hash is in big endian form.
