PKCS12_decrypt_skey() Decrypt the PKCS#8 shrouded keybag contained within bag using the supplied password pass of length passlen.

PKCS12_decrypt_skey_ex() is similar to the above but allows for a library context ctx and property query propq to be used to select algorithm implementations.

Both functions will return the decrypted key or NULL if an error occurred.
