KEYCTL(3) Linux Key Management Calls KEYCTL(3) # [NAME](#NAME) keyctl\_\*() - key management function wrappers # [DESCRIPTION](#DESCRIPTION) The **keyctl**() system call is a multiplexor for a number of key management functions. These should be called via the wrappers in the libkeyutils library. The functions can be compiled in by including the **keyutils** header file: ``` #include ``` ``` and then telling the linker it should link in the library: ``` ``` -lkeyutils ``` # [KEYCTL FUNCTIONS](#KEYCTL_FUNCTIONS) [**keyctl\_assume\_authority**(3)](/man/os/keyutils/keyctl_assume_authority.3) [**keyctl\_chown**(3)](/man/os/keyutils/keyctl_chown.3) [**keyctl\_capabilities**(3)](/man/os/keyutils/keyctl_capabilities.3) [**keyctl\_clear**(3)](/man/os/keyutils/keyctl_clear.3) [**keyctl\_describe**(3)](/man/os/keyutils/keyctl_describe.3) [**keyctl\_describe\_alloc**(3)](/man/os/keyutils/keyctl_describe_alloc.3) [**keyctl\_dh\_compute**(3)](/man/os/keyutils/keyctl_dh_compute.3) [**keyctl\_dh\_compute\_alloc**(3)](/man/os/keyutils/keyctl_dh_compute_alloc.3) [**keyctl\_get\_keyring\_ID**(3)](/man/os/keyutils/keyctl_get_keyring_ID.3) [**keyctl\_get\_persistent**(3)](/man/os/keyutils/keyctl_get_persistent.3) [**keyctl\_get\_security**(3)](/man/os/keyutils/keyctl_get_security.3) [**keyctl\_get\_security\_alloc**(3)](/man/os/keyutils/keyctl_get_security_alloc.3) [**keyctl\_instantiate**(3)](/man/os/keyutils/keyctl_instantiate.3) [**keyctl\_instantiate\_iov**(3)](/man/os/keyutils/keyctl_instantiate_iov.3) [**keyctl\_invalidate**(3)](/man/os/keyutils/keyctl_invalidate.3) [**keyctl\_join\_session\_keyring**(3)](/man/os/keyutils/keyctl_join_session_keyring.3) [**keyctl\_link**(3)](/man/os/keyutils/keyctl_link.3) [**keyctl\_move**(3)](/man/os/keyutils/keyctl_move.3) [**keyctl\_negate**(3)](/man/os/keyutils/keyctl_negate.3) [**keyctl\_pkey\_decrypt**(3)](/man/os/keyutils/keyctl_pkey_decrypt.3) [**keyctl\_pkey\_encrypt**(3)](/man/os/keyutils/keyctl_pkey_encrypt.3) [**keyctl\_pkey\_query**(3)](/man/os/keyutils/keyctl_pkey_query.3) [**keyctl\_pkey\_sign**(3)](/man/os/keyutils/keyctl_pkey_sign.3) [**keyctl\_pkey\_verify**(3)](/man/os/keyutils/keyctl_pkey_verify.3) [**keyctl\_read**(3)](/man/os/keyutils/keyctl_read.3) [**keyctl\_read\_alloc**(3)](/man/os/keyutils/keyctl_read_alloc.3) [**keyctl\_reject**(3)](/man/os/keyutils/keyctl_reject.3) [**keyctl\_restrict\_keyring**(3)](/man/os/keyutils/keyctl_restrict_keyring.3) [**keyctl\_revoke**(3)](/man/os/keyutils/keyctl_revoke.3) [**keyctl\_search**(3)](/man/os/keyutils/keyctl_search.3) [**keyctl\_session\_to\_parent**(3)](/man/os/keyutils/keyctl_session_to_parent.3) [**keyctl\_set\_reqkey\_keyring**(3)](/man/os/keyutils/keyctl_set_reqkey_keyring.3) [**keyctl\_set\_timeout**(3)](/man/os/keyutils/keyctl_set_timeout.3) [**keyctl\_setperm**(3)](/man/os/keyutils/keyctl_setperm.3) [**keyctl\_unlink**(3)](/man/os/keyutils/keyctl_unlink.3) [**keyctl\_update**(3)](/man/os/keyutils/keyctl_update.3) [**keyctl\_watch\_key**(3)](/man/os/keyutils/keyctl_watch_key.3) # [UTILITY FUNCTIONS](#UTILITY_FUNCTIONS) [**find\_key\_by\_type\_and\_name**(3)](/man/os/keyutils/find_key_by_type_and_name.3) [**recursive\_key\_scan**(3)](/man/os/keyutils/recursive_key_scan.3) [**recursive\_session\_key\_scan**(3)](/man/os/keyutils/recursive_session_key_scan.3) # [SEE ALSO](#SEE_ALSO) [**keyctl**(1)](/man/os/keyutils/keyctl.1), [**add\_key**(2)](/man/os/keyutils/add_key.2), [**keyctl**(2)](/man/os/keyutils/keyctl.2), [**request\_key**(2)](/man/os/keyutils/request_key.2), [**keyrings**(7)](/man/os/keyutils/keyrings.7), [**keyutils**(7)](/man/os/keyutils/keyutils.7) 21 Feb 2014 Linux --- Document: keyctl(3) from keyutils 1.6.3-r41 (Chainguard OS) Source: https://kernel.googlesource.com/pub/scm/linux/kernel/git/dhowells/keyutils.git
