Default behavior changes
- * Importing of RSA keys in PEM format in PSA is officially unsupported
- (this was previously undocumented).
+ * psa_import_key() now only accepts RSA keys in the PSA standard formats.
+ The undocumented ability to import other formats (PKCS#8, SubjectPublicKey,
+ PEM) accepted by the pkparse module has been removed. Applications that
+ need these format can call mbedtls_pk_parse_{public,}key() followed by
+ mbedtls_pk_import_into_psa().
-Features
- * It is possible to enable RSA support in PSA (MBEDTLS_PSA_CRYPTO_C +
- RSA_C) without enabling PK module (MBEDTLS_[PK|PK_WRITE|PK_PARSE]_C).
+Changes
+ * RSA support in PSA no longer auto-enables the pkparse and pkwrite modules,
+ saving code size when those are not otherwise enabled.
