cipher

When a Node.js request fails due to a mismatch between the TLS version and the encryption algorithm, a custom fallback encryption algorithm suite is automatically enabled to ensure the HTTPS connection is established properly.

Rule Syntax

pattern cipher://value [filters...]

Parameters	Description	Detailed Documentation
pattern	Expression to match request URLs	Match Pattern Documentation
value	Encryption algorithm (see list below) ⚠️ Loading data from files/remote URLs is not supported	Operation Instruction Documentation
filters	Optional filters, supporting matching: • Request URL/Method/Header/Content • Response Status Code/Header	Filter Documentation
