Encryption Algorithm: International Data Encryption Algorithm (IDEA)

Summary

Security
Encryption algorithm International Data Encryption Algorithm[355][356] is a block cipher[78][79][80][81] which is considered secure[357][358][359], but leading client applications do not use this algorithm. Unless your application or requirements specifically call for their use, it is generally safer to avoid cipher suites that are not adopted and supported by a critical mass of the industry.
Suggestion
Remove the cipher suite from the list of cipher suites supported by your server.
