Applications in RHEL 9 have been updated to avoid using SHA-1 in security-relevant use cases.Īmong the exceptions, the HMAC-SHA1 message authentication code and the Universal Unique Identifier (UUID) values can still be created using SHA-1 because these use cases do not currently pose security risks. The RHEL core crypto components no longer create signatures using SHA-1 by default. The digest produced by SHA-1 is not considered secure because of many documented successful attacks based on finding hash collisions. The usage of the SHA-1 message digest for cryptographic purposes has been deprecated in RHEL 9. Dynamic programming languages, web and database servers Red Hat Enterprise Linux System RolesĨ.11.
