A method of managing keys used by a digital content player on a computer system. According to the method, digital content data encrypted with a first encrypting key is decrypted using a first decrypting key, and re-encrypted using a second encrypting key. A second decrypting key is encrypted using a third encrypting key to produce an encrypted second decrypting key. In one preferred method, an encrypted first decrypting key that was encrypted using a fourth encrypting key is received, and the encrypted first decrypting key is decrypted using a fourth decrypting key to reproduce the first decrypting key. A digital content player for use on a computer system is also provided. The content player includes a decrypter that decrypts digital content data, which was encrypted with a first encrypting key, using a first decrypting key so as to produce the content data. An encrypter re-encrypts the content data using a second encrypting key and encrypts a second decrypting key using a third encrypting key. In one preferred content player, a receiver receives an encrypted first decrypting key that was encrypted using a fourth encrypting key, and the decrypter decrypts the encrypted first decrypting key using a fourth decrypting key to reproduce the first decrypting key.

1. A method of managing keys used by a digital content player on a user system, said method comprising the steps of:decrypting encrypted digital content data using a first decrypting key to produce content data, the encrypted content data having been produced by encrypting the content data with a first encrypting key; re-encrypting the content data using a second encrypting key; and encrypting a second decrypting key using a third encrypting key to produce an encrypted second decrypting key on the user system: removing the non-encrypted second decrypting key from the user system; and breaking a third decrypting key into multiple segments and storing each segment separately on the user system. wherein the first decrypting key is used to decrypt data that has been encrypted with the first encrypting key, the second decrypting key is used to decrypt data that has been encrypted with the second encrypting key, and the third decrypting key is used to decrypt data that has been encrypted with the third encrypting key.
