SIP is similar to HTTP protocol. The authentication mode is also the same. The HTTP protocol (RFC 2616) stipulates that the base mode and digest mode can be used ). RFC 2617 specifies two authentication modes. RFC 1321 is the MD5 standard. Digest is

Comments: Inline images can be encoded into base64 to reduce http requests. The disadvantage is that they cannot be cached across domains, use the readAsDataURL function in the html5 file api. This is a concept that converts a file into base64
