This dissector aim is to decrypt the whole packet if you have enough information concerning the different Security Associations.
Each kind of node may use IPsec using these two Modes. IPsec may be used in two Modes : tunnel or transport and concerns two kinds of nodes : End Nodes and Secure Gateways. The following authentication algorithms are supported: The remaining 32 bits will be used as nonce.ĭES-CBC RFC2405 with key length of 64 bits.īLOWFISH-CBC RFC2451 with key length of only 128 bits.
TripleDES-CBC RFC2451 with key length of 192 bits.ĪES-CBC with 128-bit keys RFC3602 with key length of 128/192/256 bits.ĪES-CTR RFC3686 with key length of 160/224/288 bits. The following encryption algorithms are supported: You can see if your version of Wireshark supports ESP decryption by looking for "with Gcrypt" in the about box. If Libgcrypt is linked with Wireshark you can decrypt ESP Payloads and/or Authentication Checking. ESP Payload Decryption / ESP Authentication Checking
