Representation of a MACsec Secure Association
Provides encapsulation, decapsulation, encryption, and decryption of MACsec frames
-
c_bit
()¶ returns the value of the C bit for packets sent through this SA
-
decap
(orig_pkt)¶ decapsulate a MACsec frame
-
decrypt
(orig_pkt, assoclen=None)¶ decrypt a MACsec frame for this Secure Association
-
e_bit
()¶ returns the value of the E bit for packets sent through this SA
-
encap
(pkt)¶ encapsulate a frame using this Secure Association
-
encrypt
(orig_pkt, assoclen=None)¶ encrypt a MACsec frame for this Secure Association
-
make_iv
(pkt)¶ generate an IV for the packet
-
static
shortlen
(pkt)¶ determine shortlen for a raw packet (not encapsulated yet)
-
static
split_pkt
(pkt, assoclen, icvlen=0)¶ split the packet into associated data, plaintext or ciphertext, and optional ICV
