Not recommended. Verification of ASN.1 DER-encoded ECDSA signatures using the P-384 curve and SHA-256.

In most situations, P-256 should be used only with SHA-256 and P-384 should be used only with SHA-384. However, in some cases, particularly TLS on the web, it is necessary to support P-256 with SHA-384 for compatibility with widely-deployed implementations that do not follow these guidelines.

See "ECDSA_*_ASN1 Details" in ring::signature's module-level documentation for more details.
