79  *
80  *     VERSION is only present if there are multiple versions of

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