  61  * For the algorithm names, we use the following formula for our primary

  63  *
  64  *     ALGNAME[VERSION?][-SUBNAME[VERSION?]?][-SIZE?][-MODE?]
  65  *
  66  *     VERSION is only present if there are multiple versions of
  67  *     an alg (MD2, MD4, MD5).  It may be omitted if there is only
  68  *     one version (if a subsequent version is released in the future,
  69  *     we can always change the canonical name, and add the old name
  70  *     as an alias).
  71  *
  72  *     SUBNAME may be present where we are combining multiple
  73  *     algorithms together, e.g. MD5-SHA1.
  74  *
  75  *     SIZE is only present if multiple versions of an algorithm exist
  76  *     with different sizes (e.g. AES-128-CBC, AES-256-CBC)
  77  *
  78  *     MODE is only present where applicable.
  79  *
  80  * We add diverse other names where applicable, such as the names that
  81  * NIST uses, or that are used for ASN.1 OBJECT IDENTIFIERs, or names
  82  * we have used historically.
  83  *
  84  * Algorithm names are case insensitive, but we use all caps in our "canonical"
  85  * names for consistency.
