These locks are not exposed any more. You will need to rewrite your code to not need this function. There are some new lock related functions that exist that are essentially thin wrappers around the platform threading library that is in use. Depending on what you need it for they might suffice: CRYPTO_RWLOCK *CRYPTO_THREAD_lock_new(void); int CRYPTO_THREAD_read_lock(CRYPTO_RWLOCK *lock); int CRYPTO_THREAD_write_lock(CRYPTO_RWLOCK *lock); int CRYPTO_THREAD_unlock(CRYPTO_RWLOCK *lock); void CRYPTO_THREAD_lock_free(CRYPTO_RWLOCK *lock); https://www.openssl.org/docs/man1.1.1/man3/CRYPTO_THREAD_lock_new.html > > RSA_PKCS1_SSLeay Now called RSA_PKCS1_OpenSSL(). > DH_get_ex_new_index> DSA_get_ex_new_index > RSA_get_ex_new_index All of these still exist but were just converted from functions to macros.
