What Types of Certificate Algorithms Do Lexmark Printers Support?

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:

Product announced year	Printer models
2012 Products	MS31x, MS41x, MS51x, MS61x, MS71x, MS81x, MS91x, MX31x, MX41x, MX51x, MX61x, MX71x, MX81x, MX91x, CS31x, CS41x, CS51x, CX31x, CX41x, CX51x
2016 Products	CS720, CS725, CS820, C6160, CX725, CX820, CX825, CX860, XC6152, XC8155, XC8160

IMPORTANT!

For users who have older printer models and want to use the SHA384 and SHA512 hash functions, a Special Product Request (SPR) process is necessary to proceed. Please contact Lexmark Technical Support for assessment and more information.

NOTE:

Fees may apply for a SPR.
