# NAME

OpenSSL_add_all_algorithms, OpenSSL_add_all_ciphers, OpenSSL_add_all_digests, EVP_cleanup - add algorithms to internal table

# SYNOPSIS

     #include <openssl/evp.h>

Deprecated:

     # if OPENSSL_API_COMPAT < 0x10100000L
     void OpenSSL_add_all_algorithms(void);
     void OpenSSL_add_all_ciphers(void);
     void OpenSSL_add_all_digests(void);

     void EVP_cleanup(void)
    # endif

# DESCRIPTION

OpenSSL keeps an internal table of digest algorithms and ciphers. It uses this table to lookup ciphers via functions such as `EVP_get_cipher_byname()`.

`OpenSSL_add_all_digests()` adds all digest algorithms to the table.

`OpenSSL_add_all_algorithms()` adds all algorithms to the table (digests and ciphers).

`OpenSSL_add_all_ciphers()` adds all encryption algorithms to the table including password based encryption algorithms.

In versions prior to 1.1.0 `EVP_cleanup()` removed all ciphers and digests from the table. It no longer has any effect in OpenSSL 1.1.0.

# RETURN VALUES

None of the functions return a value.

# SEE ALSO

evp(7), EVP_DigestInit(3), EVP_EncryptInit(3)

# HISTORY

The `OpenSSL_add_all_algorithms()`, `OpenSSL_add_all_ciphers()`, `OpenSSL_add_all_digests()`, and `EVP_cleanup()`, functions were deprecated in OpenSSL 1.1.0 by `OPENSSL_init_crypto()` and should not be used.
