Hi, I'm trying to set up ipsec-protected gre tunnel from OpenBSD to Cisco, and - not only thanks to all the useful advices I got in my earlier thread https://marc.info/?l=openbsd-misc&m=145043287011537&w=2, but also 10x to http://bsdsupport.org/setting-up-ipsec-over-gre-on-openbsd/ - I've so far managed to successfully establish non-protected gre tunnel. Also OSPF works through it!
I want to dive further into ipsec and rsa keys (which BTW I have successfully configured numerous times in OpenBSD - OpenBSD and Cisco - Cisco setups, but never in a OpenBSD - Cisco setup), but I've stumbled upon an obstacle I haven't encountered before: Cisco asks for public keys in hex number format, similar to: 30819F30 0D06092A 864886F7 0D010101 05000381 8D003081 89028181 00B2GD66 569171F2 0BCEAE31 5DCDD33A AA3E908C C93A46ED 267AA65A 70150BEC F0BAF97C 3348DDAB 7FB26194 739D3BB2 4114F5BC 87A1F8BD 67DD656C 34540314 0EAD1301 40A4FB2C B37438F3 F37F8182 C0C0286C 1200F3A0 73E2D021 D9CAFE2C 547CABCF 43ED95EE 12C9B4C0 633DA4C4 D7FAF832 31F7AFEA C88DCDCB BBB735D9 CB020301 0001 ... while OpenBSD's local.pub is similar to: -----BEGIN PUBLIC KEY----- MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ9AMIIBCgKCAQEAtBdefJzPO8VhBUx28wLV xLk0DeLDTIDU6m+v7DCC1dge3NLK2i+G5wkqUvlOK/vmPkKRydOzioViUiwhoP1q q6oHE8aQvVCbD7R6lMibx+4Rcejwc3pBzx5K1ibCqj9zhkrVI1SD5PIMAyBF/WxG rR47c+cXZwwUFspXBddqODaJcH9pFKW1gUhMo58j8MVw2HYyMdQo7nbx5TKybUWd 9+skXFiTqWumZGqV2OsKqVKsWmbq6jojUwpobRgEXqj0ndHKsGK39YP/XqAx8nYm pAkaDvFmCE4ntoVHoG/nfKtgpryPEb1nQ3e1t97WgoJUOw3iqutji3XQ+/tDfvWq HQIDAQAB -----END PUBLIC KEY----- Any idea on how to convert OpenBSD's /etc/isakmpd/local.pub to hex number format?
