Defined in:

lib/net/imap/authenticators/cram_md5.rb

Overview

Authenticator for the “CRAM-MD5” SASL mechanism, specified in RFC2195. See Net::IMAP#authenticate.

Deprecated

CRAM-MD5 is obsolete and insecure. It is included for compatibility with existing servers. draft-ietf-sasl-crammd5-to-historic recommends using SCRAM-* or PLAIN protected by TLS instead.

Additionally, RFC8314 discourage the use of cleartext and recommends TLS version 1.2 or greater be used for all traffic. With TLS CRAM-MD5 is okay, but so is PLAIN
