                                const gnutls_crypto_cipher_st *s);

This function will register a cipher interface to be used by gnutls. Any interface registered will override the included engine and by convention kernel implemented interfaces should have priority of 90. The interface with the lowest priority will be used by gnutls.

This function should be called before gnutls_global_init().

For simplicity you can use the convenience gnutls_crypto_cipher_register() macro.

Parameters

priority

is the priority of the cipher interface

 

version

should be set to GNUTLS_CRYPTO_API_VERSION

 

s

is a structure holding new interface's data

 

Returns

GNUTLS_E_SUCCESS on success, otherwise an error.

Since: 2.6.0

This function will register a digest interface to be used by gnutls. Any interface registered will override the included engine and by convention kernel implemented interfaces should have priority of 90. The interface with the lowest priority will be used by gnutls.

This function should be called before gnutls_global_init().

For simplicity you can use the convenience gnutls_crypto_digest_register() macro.

Parameters

priority

is the priority of the digest interface

gnutls_crypto_rnd_register2 ()

int
gnutls_crypto_rnd_register2 (int priority,
                             int version,
                             const gnutls_crypto_rnd_st *s);

This function will register a random generator to be used by gnutls. Any generator registered will override the included generator and by convention kernel implemented generators have priority of 90. The generator with the lowest priority will be used by gnutls.

This function should be called before gnutls_global_init().

For simplicity you can use the convenience gnutls_crypto_rnd_register() macro.

Parameters

priority

is the priority of the generator

 

version

should be set to GNUTLS_CRYPTO_API_VERSION

 

s

is a structure holding new generator's data

 

Returns

GNUTLS_E_SUCCESS on success, otherwise an error.

Since: 2.6.0


gnutls_crypto_pk_register2 ()

int
gnutls_crypto_pk_register2 (int priority,
                            int version,
                            const gnutls_crypto_pk_st *s);

This function will register an interface for gnutls to operate on public key operations. Any interface registered will override the included interface. The interface with the lowest priority will be used by gnutls.

Note that the bigint interface must interoperate with the bigint interface. Thus if this interface is updated the gnutls_crypto_bigint_register() should also be used.

This function should be called before gnutls_global_init().

For simplicity you can use the convenience gnutls_crypto_pk_register() macro.

Parameters

priority

is the priority of the interface

 

version

should be set to GNUTLS_CRYPTO_API_VERSION

 

s

is a structure holding new interface's data

 

Returns

GNUTLS_E_SUCCESS on success, otherwise an error.

Since: 2.6.0


gnutls_crypto_bigint_register2 ()

int
gnutls_crypto_bigint_register2 (int priority,

                                const gnutls_crypto_bigint_st *s);

This function will register an interface for gnutls to operate on big integers. Any interface registered will override the included interface. The interface with the lowest priority will be used by gnutls.

Note that the bigint interface must interoperate with the public key interface. Thus if this interface is updated the gnutls_crypto_pk_register() should also be used.

This function should be called before gnutls_global_init().

For simplicity you can use the convenience gnutls_crypto_bigint_register() macro.

Parameters

priority

is the priority of the interface

 

version

should be set to GNUTLS_CRYPTO_API_VERSION

 

s
