For ease of comparison, heres the sequence of expected hashes, copied from the Bitcoin wiki example: public key: sHA256: A447BDB2D98D4B408, ripemd160: D5567439E5E39F86A0D273BEE prepend 0x00: D5567439E5E39F86A0D273BEE, sHA256: 445C7A8007A93D SHA256 (checksum is first 4 bytes step 4 result checksum (hex) address. Address utility screen, address screen. Clicking the arrows performs conversions in the direction of the arrow. The third argument is the output byte array. This screen is especially useful for discovering what hexadecimal prefix is required to create Base58Check strings with a specific prefix, or for seeing what is encoded in non-standard Base58 strings generated by service providers. Once the hexadecimal equivalent is known, simply making an insignificant change to the hex box (such as adding a space to the end) will result in the correct checksum being recomputed and displayed.
