| [49f147b] | 12 | .SH DESCRPTION |
|---|
| 13 | traceanon anonymises a trace by replacing IP addresses found in the IP header, |
|---|
| 14 | and any embedded packets inside an ICMP packet. It also fixes the checksums |
|---|
| 15 | inside TCP and UDP headers. |
|---|
| 16 | |
|---|
| 17 | Two anonymisation schemes are supported, the first replaces a prefix with |
|---|
| 18 | another prefix. This can be used for instance to replace a /16 with the |
|---|
| 19 | equivilent prefix from RFC1918. The other scheme is cryptopan which is a |
|---|
| 20 | prefix preserving encryption scheme based on AES. |

| 51 | encrypt the IP addresses using the prefix-preserving cryptopan method using |
|---|
| 52 | the key "key". The key can be up to 32 bytes long, and will be padded with |
|---|
| 53 | NUL charactors. |

| 65 | .SH BUGS |
|---|
| 66 | This software should support encrypting based on the direction/interface flag. |
|---|
| 67 | |
|---|
| [eb6f2ea] | 68 | IP addresses inside ARP's are not encrypted. |
