<p class="MsoNormal">Hi All,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m using RHEL 6.6 and openswan-2.6.32-37.el6.x86_64<o:p></o:p></p>
<p class="MsoNormal">I had a couple of questions related to ciphers:<o:p></o:p></p>
<p class="MsoNormal">1 - When I run the ipsec auto –status, I do see Blowfish listed as one of the available ciphers:<o:p></o:p></p>
<p class="MsoNormal">ipsec auto --status | grep BLOW<o:p></o:p></p>
<p class="MsoNormal">000 algorithm ESP encrypt: id=7, name=ESP_BLOWFISH, ivlen=8, keysizemin=40, keysizemax=448<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">However, when I plug this into my config file, the tunnel does not come up. Could you please let me know if Blowfish is something which is unsupported<o:p></o:p></p>
<p class="MsoNormal"><snip><o:p></o:p></p>
<p class="MsoNormal"> esp=blowfish448-sha1<o:p></o:p></p>
<p class="MsoNormal"></snip><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">2 – I believe esp cipher can be specified as follows<o:p></o:p></p>
<p class="MsoNormal"> aes-sha1 OR<o:p></o:p></p>
<p class="MsoNormal"> aes128-sha1<o:p></o:p></p>
<p class="MsoNormal">How does OpenSwan treat these 2 internally. Are they treated as 2 separate ciphers or the same one?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Regards,<o:p></o:p></p>
