- add struct RsaPadding to pass padding information to CryptoCb - OAEP decryption: struct RsaPadding is used to return 'unpadded' status flag to skip software unpadding - wc_pkcs11.h: add utility functions to map wc constants to CKM constants (hash / mgf)
- add support for RSA_PKCS, RSA_PKCS_PSS, RSA_PKCS_OAEP - support private key sign: RSA_PKCS, RSA_PKCS_PSS - support private key encrypt: RSA_PKCS_OAEP - no support for token public key PKCS - compile-time gated by -DNO_PKCS11_RSA_PKCS
- add version of wc_CryptoCb_Rsa that includes padding information for use by device callback
- adds support for passing padding information to RSA callback for device-supported RSA padding. - compile-time gated by -DWOLF_CRYPTO_CB_NOPAD

1. BasicConstraints pathLenConstraint absent vs. 0 — get_ext_d2i/set_ext/V3_EXT_d2i now distinguish "no constraint" from 0 per RFC 5280 §4.2.1.9, using the existing basicConstPlSet flag. 2. GENERAL_NAME_print GEN_DIRNAME — added missing return-value normalization so the directory name is actually printed (was emitting only DirName:). 3. GENERAL_NAME_print GEN_DNS — use ASN1_STRING_print like the EMAIL/URI cases, avoiding NULL-strData deref and NUL-truncation. 4. X509_print BasicConstraints — print , pathlen:N to match OpenSSL. 5. X509_print Extended Key Usage — print Any Extended Key Usage (was omitted). 6. get_ext_d2i CRL_DIST_OID double-free — null gn immediately after ownership transfers to dp, so an error from the next push doesn't free it twice. 7. X509V3_EXT_print SAN truncation/failure — match XSNPRINTF size cap to the allocation; was truncating at indent==1 and failing at indent>=2. 8. X509V3_EXT_print AUTH_KEY/SUBJ_KEY NULL deref — NULL-check i2s_ASN1_STRING return before passing to %s. 9. X509_add_ext SAN type confusion — reject DIRNAME/RID/X400/EDIPARTY; only the ASN1_STRING*-backed types are read via gn->d.ia5. Was performing a wild-pointer XMEMCPY in add_altname_ex. Also: extracted the SAN and WOLFSSL_CUSTOM_OID arms of X509_add_ext into static helpers (behavior-preserving). Regression tests added for #1–5 and wolfSSL#9; existing GENERAL_NAME_print test hardened (gives GEN_DIRNAME a real directoryName, eliminating an OOB read that the print fix would otherwise expose).
