encrypt_cryptopan

Pseudonymizes fields according to a given method.

Synopsis​

encrypt_cryptopan(address:ip, [seed=str])

Description​

Anonymizes IP Addresses using the Crypto-PAn algorithm.

address: ip​

The IP Address to anonymize.

seed = str (optional)​

A 64-byte seed that describes a hexadecimal value. When the seed is shorter than 64 bytes, the operator will append zeros to match the size; when it is longer, it will truncate the seed.

Example​

Anonymize all values of the fields src_ip and dst_ip using the crypto-pan algorithm and the seed "deadbeef":

from { src_ip: 114.13.11.35, dst_ip: 114.56.11.200 }
src_ip = encrypt_cryptopan(src_ip, seed="deadbeef")
dst_ip = encrypt_cryptopan(dst_ip, seed="deadbeef")
write_json
Anonymized
{
  "src_ip": "117.179.11.60",
  "dst_ip": "117.135.244.180"
}
