Damien Miller | 450a7a1 | 2000-03-26 13:04:51 +1000 | [diff] [blame] | 101 | to store the private key. |
| 102 | The public key is stored in a file with the same name but |

Damien Miller | 450a7a1 | 2000-03-26 13:04:51 +1000 | [diff] [blame] | 104 | appended. |
| 105 | The program also asks for a passphrase. |
| 106 | The passphrase may be empty to indicate no passphrase |
Ben Lindstrom | bf555ba | 2001-01-18 02:04:35 +0000 | [diff] [blame] | 107 | (host keys must have an empty passphrase), or it may be a string of |
Damien Miller | 450a7a1 | 2000-03-26 13:04:51 +1000 | [diff] [blame] | 108 | arbitrary length. |
| 109 | Good passphrases are 10-30 characters long and are |
Damien Miller | 32aa144 | 1999-10-29 09:15:49 +1000 | [diff] [blame] | 110 | not simple sentences or otherwise easily guessable (English |

| 113 | The passphrase can be changed later by using the |

Damien Miller | 450a7a1 | 2000-03-26 13:04:51 +1000 | [diff] [blame] | 117 | There is no way to recover a lost passphrase. |

Damien Miller | 32aa144 | 1999-10-29 09:15:49 +1000 | [diff] [blame] | 119 | lost or forgotten, you will have to generate a new key and copy the |
| 120 | corresponding public key to other machines. |

Ben Lindstrom | 5a70782 | 2001-04-22 17:15:46 +0000 | [diff] [blame] | 122 | For RSA1 keys, |
| 123 | there is also a comment field in the key file that is only for |
Damien Miller | 450a7a1 | 2000-03-26 13:04:51 +1000 | [diff] [blame] | 124 | convenience to the user to help identify the key. |
| 125 | The comment can tell what the key is for, or whatever is useful. |
| 126 | The comment is initialized to |
