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

  75  *
  76  *     ALGNAME[VERSION?][-SUBNAME[VERSION?]?][-SIZE?][-MODE?]
  77  *
  78  *     VERSION is only present if there are multiple versions of
  79  *     an alg (MD2, MD4, MD5).  It may be omitted if there is only
  80  *     one version (if a subsequent version is released in the future,
  81  *     we can always change the canonical name, and add the old name
  82  *     as an alias).
  83  *
  84  *     SUBNAME may be present where we are combining multiple
  85  *     algorithms together, e.g. MD5-SHA1.
  86  *
  87  *     SIZE is only present if multiple versions of an algorithm exist
  88  *     with different sizes (e.g. AES-128-CBC, AES-256-CBC)
  89  *
  90  *     MODE is only present where applicable.
  91  *
  92  * We add diverse other names where applicable, such as the names that
  93  * NIST uses, or that are used for ASN.1 OBJECT IDENTIFIERs, or names
  94  * we have used historically.
  95  *
  96  * Algorithm names are case insensitive, but we use all caps in our "canonical"
  97  * names for consistency.
