OSSL_HPKE_str2suite() maps input I<str> strings to an B<OSSL_HPKE_SUITE> object.
The input I<str> should be a comma-separated string with a KEM,
-KDF and AEAD name in that order, for example "x25519,hkdf-sha256,aes128gcm".
+KDF and AEAD name in that order, for example "x25519,hkdf-sha256,aes-128-gcm".
This can be used by command line tools that accept string form names for HPKE
codepoints. Valid (case-insensitive) names are:
"p-256", "p-384", "p-521", "x25519" and "x448" for KEM,
"hkdf-sha256", "hkdf-sha384" and "hkdf-sha512" for KDF, and
-"aes-gcm-128", "aes-gcm-256", "chacha20-poly1305" and "exporter" for AEAD.
+"aes-128-gcm", "aes-256-gcm", "chacha20-poly1305" and "exporter" for AEAD.
String variants of the numbers listed in L</OSSL_HPKE_SUITE Identifiers>
can also be used.
