Well 48 = ASCII '0' so it seems like your data really is in hex format. You'll need to convert it to a binary file first either by writing a program or using a utility: IIRC the xxd utility can do this. After that it depends on what format the data is in. If its a subjectPublicKeyInfo structure OpenSSL should have no problems with it. If its and RSAPublicKey you'll need to convert it because currently there's no command line options to handle that.
