Lexmark MX617
Overview:
A " Signature algorithm not supported" error message implies that the certificate type used in the printer is not supported.
Certificate algorithms:
Because of the recently found vulnerabilities on SHA1 certificates, users are now moving to SHA2 certificates.
SHA2
has four kinds of hash functions:
SHA224
SHA256
SHA384
SHA512
Although Lexmark printers support the SHA2 certificate, not all of them support all hash functions, especially SHA384 and SHA512.
Printer models that support SHA384 and SHA512:
Here are the list of printers that support SHA384 and SHA512:
