Should change decode table to seamlessly decode URL Safe stuff.

You need to add a 62 and 63 once more to the decode table: (see above link)

// Note: '+' and '-' both decode to 62. '/' and '_' both decode to 63. This means decoder seamlessly handles both
//URL_SAFE and STANDARD base64. (The encoder, on the other hand, needs to know ahead of time what to emit).
//private static final byte[] DECODE_TABLE = {

For my purposes, I wanted full speed for encoding to URL_SAFE, so I added a new encode look up table, and then

static const char base64EncodingTable_URL_SAFE[64] = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-";

• (NSString *)encodeBase64WithData_URL_SAFE:(NSData *)objData {
  return [self encodeBase64WithData:objData table:_base64EncodingTable_URL_SAFE];
  }
• (NSString *)encodeBase64WithData:(NSData *)objData {
  return [self encodeBase64WithData:objData table:_base64EncodingTable];
  }
