New WordPress Version and Plugins Will Not Update

I get this error message when trying to update plugins:
“Download failed. error:0D0890A1:asn1 encoding routines:ASN1_verify:unknown message digest algorithm”

I get this message trying to update to latest version of WP:
“Downloading update from http://downloads.wordpress.org/release/wordpress-4.3-no-content.zip…
Download failed.: error:0D0890A1:asn1 encoding routines:ASN1_verify:unknown message digest algorithm
Installation Failed”

I’ve never had a problem with this in the past.
