Description Josh Glover (RETIRED) gentoo-dev 2004-04-29 07:12:45 UTC
No mention is made in the install section of the Gentoo Handbook (see the URL associated with this bug) of the fact that the LiveCD (and now PackageCD) ISOs are GPG-signed. There is a paragraph on checking MD5 sums. I suggest the following revision:

In case you wonder if your downloaded file is corrupted or not, you can check its MD5 checksum and compare it with the MD5 checksum we provide (such as install-x86-minimal-2004.1.iso.md5). You can check the MD5 checksum with the md5sum tool under Linux/Unix or md5summer for Windows.

+ Another way to check the validity of the downloaded file is to use GnuPG to
+ verify the cryptographic signature that we provide (such as 
+ install-x86-minimal-2004.1.iso.asc). Download the signature file, then obtain
+ our public key:
+
+ gpg --keyserver pgp.mit.edu --recv-keys 19462D47
+
+ Now, verify the signature:
+
+ gpg --verify install-x86-minimal-2004.1.iso.asc \
+     install-x86-minimal-2004.1.iso.asc
+
+ If the signature is good, you should see something like the following:
+
+ gpg: Signature made Mon Apr 19 18:54:40 2004 EDT using DSA key ID 19462D47
+ gpg: Good signature from "John Davis (Gentoo Linux Developer) <zhen@gentoo.org>"
+ gpg:                 aka "Gentoo Linux Release Enginneering <releng@gentoo.org>"

To burn the downloaded ISO(s), you have to select raw-burning. How you do this is highly program-dependent. We will discuss a couple of popular tools on how to do this.

Fixed in CVS. Thanks for the quick diff :)
