See \fIprovider\fR\|(7) for further information. .PP The \s-1CIPHER\s0 operation enables providers to implement cipher algorithms and make them available to applications via the \s-1API\s0 functions \fIEVP_EncryptInit_ex\fR\|(3), \&\fIEVP_EncryptUpdate\fR\|(3) and \fIEVP_EncryptFinal\fR\|(3) (as well as the decrypt equivalents and other related functions). .PP All \*(L"functions\*(R" mentioned here are passed as function pointers between \&\fIlibcrypto\fR and the provider in \fB\s-1OSSL_DISPATCH\s0\fR arrays via \&\fB\s-1OSSL_ALGORITHM\s0\fR arrays that are returned by the provider's \&\fIprovider_query_operation()\fR function (see \*(L"Provider Functions\*(R" in \fIprovider\-base\fR\|(7)). .PP All these \*(L"functions\*(R" have a corresponding function type definition named \fBOSSL_FUNC_{name}_fn\fR, and a helper function to retrieve the function pointer from an \fB\s-1OSSL_DISPATCH\s0\fR element named \&\fBOSSL_FUNC_{name}\fR. For example, the \*(L"function\*(R" \fIOSSL_FUNC_cipher_newctx()\fR has these: .PP .Vb 3 \& typedef void *(OSSL_FUNC_cipher_newctx_fn)(void *provctx); \& static ossl_inline OSSL_FUNC_cipher_newctx_fn \& OSSL_FUNC_cipher_newctx(const OSSL_DISPATCH *opf); .Ve .PP \&\fB\s-1OSSL_DISPATCH\s0\fR arrays are indexed by numbers that are provided as macros in \fIopenssl\-core_dispatch.h\fR\|(7), as follows: .PP .Vb 3 \& OSSL_FUNC_cipher_newctx OSSL_FUNC_CIPHER_NEWCTX \& OSSL_FUNC_cipher_freectx OSSL_FUNC_CIPHER_FREECTX \& OSSL_FUNC_cipher_dupctx OSSL_FUNC_CIPHER_DUPCTX \& \& OSSL_FUNC_cipher_encrypt_init OSSL_FUNC_CIPHER_ENCRYPT_INIT \& OSSL_FUNC_cipher_decrypt_init OSSL_FUNC_CIPHER_DECRYPT_INIT \& OSSL_FUNC_cipher_update OSSL_FUNC_CIPHER_UPDATE \& OSSL_FUNC_cipher_final OSSL_FUNC_CIPHER_FINAL \& OSSL_FUNC_cipher_cipher OSSL_FUNC_CIPHER_CIPHER \& \& OSSL_FUNC_cipher_get_params OSSL_FUNC_CIPHER_GET_PARAMS \& OSSL_FUNC_cipher_get_ctx_params OSSL_FUNC_CIPHER_GET_CTX_PARAMS \& OSSL_FUNC_cipher_set_ctx_params OSSL_FUNC_CIPHER_SET_CTX_PARAMS \& \& OSSL_FUNC_cipher_gettable_params OSSL_FUNC_CIPHER_GETTABLE_PARAMS \& OSSL_FUNC_cipher_gettable_ctx_params OSSL_FUNC_CIPHER_GETTABLE_CTX_PARAMS \& OSSL_FUNC_cipher_settable_ctx_params OSSL_FUNC_CIPHER_SETTABLE_CTX_PARAMS .Ve .PP A cipher algorithm implementation may not implement all of these functions. In order to be a consistent set of functions there must at least be a complete set of \*(L"encrypt\*(R" functions, or a complete set of \*(L"decrypt\*(R" functions, or a single \*(L"cipher\*(R" function. In all cases both the OSSL_FUNC_cipher_newctx and OSSL_FUNC_cipher_freectx functions must be present. All other functions are optional. .SS "Context Management Functions" .IX Subsection "Context Management Functions" \&\fIOSSL_FUNC_cipher_newctx()\fR should create and return a pointer to a provider side structure for holding context information during a cipher operation. A pointer to this context will be passed back in a number of the other cipher operation function calls. The parameter \fIprovctx\fR is the provider context generated during provider initialisation (see \fIprovider\fR\|(7)). .PP \&\fIOSSL_FUNC_cipher_freectx()\fR is passed a pointer to the provider side cipher context in the \fIcctx\fR parameter. This function should free any resources associated with that context. .PP \&\fIOSSL_FUNC_cipher_dupctx()\fR should duplicate the provider side cipher context in the \&\fIcctx\fR parameter and return the duplicate copy. .SS "Encryption/Decryption Functions" .IX Subsection "Encryption/Decryption Functions" \&\fIOSSL_FUNC_cipher_encrypt_init()\fR initialises a cipher operation for encryption given a newly created provider side cipher context in the \fIcctx\fR parameter. The key to be used is given in \fIkey\fR which is \fIkeylen\fR bytes long. The \s-1IV\s0 to be used is given in \fIiv\fR which is \fIivlen\fR bytes long. The \fIparams\fR, if not \s-1NULL,\s0 should be set on the context in a manner similar to using \fIOSSL_FUNC_cipher_set_ctx_params()\fR. .PP \&\fIOSSL_FUNC_cipher_decrypt_init()\fR is the same as \fIOSSL_FUNC_cipher_encrypt_init()\fR except that it initialises the context for a decryption operation. .PP \&\fIOSSL_FUNC_cipher_update()\fR is called to supply data to be encrypted/decrypted as part of a previously initialised cipher operation. The \fIcctx\fR parameter contains a pointer to a previously initialised provider side context. \&\fIOSSL_FUNC_cipher_update()\fR should encrypt/decrypt \fIinl\fR bytes of data at the location pointed to by \fIin\fR. The encrypted data should be stored in \fIout\fR and the amount of data written to \&\fI*outl\fR which should not exceed \fIoutsize\fR bytes. \&\fIOSSL_FUNC_cipher_update()\fR may be called multiple times for a single cipher operation. It is the responsibility of the cipher implementation to handle input lengths that are not multiples of the block length. In such cases a cipher implementation will typically cache partial blocks of input data until a complete block is obtained. \&\fIout\fR may be the same location as \fIin\fR but it should not partially overlap. The same expectations apply to \fIoutsize\fR as documented for \&\fIEVP_EncryptUpdate\fR\|(3) and \fIEVP_DecryptUpdate\fR\|(3). .PP \&\fIOSSL_FUNC_cipher_final()\fR completes an encryption or decryption started through previous \&\fIOSSL_FUNC_cipher_encrypt_init()\fR or \fIOSSL_FUNC_cipher_decrypt_init()\fR, and \fIOSSL_FUNC_cipher_update()\fR calls. The \fIcctx\fR parameter contains a pointer to the provider side context. Any final encryption/decryption output should be written to \fIout\fR and the amount of data written to \fI*outl\fR which should not exceed \fIoutsize\fR bytes. The same expectations apply to \fIoutsize\fR as documented for \&\fIEVP_EncryptFinal\fR\|(3) and \fIEVP_DecryptFinal\fR\|(3). .PP \&\fIOSSL_FUNC_cipher_cipher()\fR performs encryption/decryption using the provider side cipher context in the \fIcctx\fR parameter that should have been previously initialised via a call to \fIOSSL_FUNC_cipher_encrypt_init()\fR or \fIOSSL_FUNC_cipher_decrypt_init()\fR. This should call the raw underlying cipher function without any padding. This will be invoked in the provider as a result of the application calling \&\fIEVP_Cipher\fR\|(3). The application is responsible for ensuring that the input is a multiple of the block length. The data to be encrypted/decrypted will be in \fIin\fR, and it will be \fIinl\fR bytes in length. The output from the encryption/decryption should be stored in \fIout\fR and the amount of data stored should be put in \fI*outl\fR which should be no more than \&\fIoutsize\fR bytes. .SS "Cipher Parameters" .IX Subsection "Cipher Parameters" See \s-1\fIOSSL_PARAM\s0\fR\|(3) for further details on the parameters structure used by these functions. .PP \&\fIOSSL_FUNC_cipher_get_params()\fR gets details of the algorithm implementation and stores them in \fIparams\fR. .PP \&\fIOSSL_FUNC_cipher_set_ctx_params()\fR sets cipher operation parameters for the provider side cipher context \fIcctx\fR to \fIparams\fR. Any parameter settings are additional to any that were previously set. Passing \s-1NULL\s0 for \fIparams\fR should return true. .PP \&\fIOSSL_FUNC_cipher_get_ctx_params()\fR gets cipher operation details details from the given provider side cipher context \fIcctx\fR and stores them in \fIparams\fR. Passing \s-1NULL\s0 for \fIparams\fR should return true. .PP \&\fIOSSL_FUNC_cipher_gettable_params()\fR, \fIOSSL_FUNC_cipher_gettable_ctx_params()\fR, and \fIOSSL_FUNC_cipher_settable_ctx_params()\fR all return constant \fB\s-1OSSL_PARAM\s0\fR arrays as descriptors of the parameters that \fIOSSL_FUNC_cipher_get_params()\fR, \&\fIOSSL_FUNC_cipher_get_ctx_params()\fR, and \fIOSSL_FUNC_cipher_set_ctx_params()\fR can handle, respectively. \fIOSSL_FUNC_cipher_gettable_ctx_params()\fR and \&\fIOSSL_FUNC_cipher_settable_ctx_params()\fR will return the parameters associated with the provider side context \fIcctx\fR in its current state if it is not \s-1NULL. \s0 Otherwise, they return the parameters associated with the provider side algorithm \fIprovctx\fR. .PP Parameters currently recognised by built-in ciphers are listed in \&\*(L"\s-1PARAMETERS\*(R"\s0 in \fIEVP_EncryptInit\fR\|(3). Not all parameters are relevant to, or are understood by all ciphers. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fIOSSL_FUNC_cipher_newctx()\fR and \fIOSSL_FUNC_cipher_dupctx()\fR should return the newly created provider side cipher context, or \s-1NULL\s0 on failure. .PP \&\fIOSSL_FUNC_cipher_encrypt_init()\fR, \fIOSSL_FUNC_cipher_decrypt_init()\fR, \fIOSSL_FUNC_cipher_update()\fR, \&\fIOSSL_FUNC_cipher_final()\fR, \fIOSSL_FUNC_cipher_cipher()\fR, \fIOSSL_FUNC_cipher_get_params()\fR, \&\fIOSSL_FUNC_cipher_get_ctx_params()\fR and \fIOSSL_FUNC_cipher_set_ctx_params()\fR should return 1 for success or 0 on error. .PP \&\fIOSSL_FUNC_cipher_gettable_params()\fR, \fIOSSL_FUNC_cipher_gettable_ctx_params()\fR and \&\fIOSSL_FUNC_cipher_settable_ctx_params()\fR should return a constant \fB\s-1OSSL_PARAM\s0\fR array, or \s-1NULL\s0 if none is offered. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fIprovider\fR\|(7), \s-1\fIOSSL_PROVIDER\-FIPS\s0\fR\|(7), \fIOSSL_PROVIDER\-default\fR\|(7), \&\fIOSSL_PROVIDER\-legacy\fR\|(7), \&\s-1\fIEVP_CIPHER\-AES\s0\fR\|(7), \s-1\fIEVP_CIPHER\-ARIA\s0\fR\|(7), \s-1\fIEVP_CIPHER\-BLOWFISH\s0\fR\|(7), \&\s-1\fIEVP_CIPHER\-CAMELLIA\s0\fR\|(7), \s-1\fIEVP_CIPHER\-CAST\s0\fR\|(7), \s-1\fIEVP_CIPHER\-CHACHA\s0\fR\|(7), \&\s-1\fIEVP_CIPHER\-DES\s0\fR\|(7), \s-1\fIEVP_CIPHER\-IDEA\s0\fR\|(7), \s-1\fIEVP_CIPHER\-RC2\s0\fR\|(7), \&\s-1\fIEVP_CIPHER\-RC4\s0\fR\|(7), \s-1\fIEVP_CIPHER\-RC5\s0\fR\|(7), \s-1\fIEVP_CIPHER\-SEED\s0\fR\|(7), \&\s-1\fIEVP_CIPHER\-SM4\s0\fR\|(7), \&\fIlife_cycle\-cipher\fR\|(7), \fIEVP_EncryptInit\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" The provider \s-1CIPHER\s0 interface was introduced in OpenSSL 3.0. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2019\-2022 The OpenSSL Project Authors.
