-     * The sn (short names) and ln (long names) are defined in
-     * <openssl/object.h> and <openssl/obj_mac.h>. They are textual
-     * representations of ASN.1 OBJECT IDENTIFIERs. Each supported digest
-     * algorithm has an OBJECT IDENTIFIER associated to it and those again
-     * have short/long names assigned to them.
-     * E.g. the OBJECT IDENTIFIER for SHA-1 is 1.3.14.3.2.26 and its
-     * sn is "SHA1" and its ln is "sha1".
