The contents of this data is specific to the +particular implementation of the cipher. For example this data can be used by +engines to store engine specific information. The data is automatically +allocated and freed by OpenSSL, so applications and engines should not normally +free this directly (but see below). +.PP +The \fBEVP_CIPHER_CTX_set_cipher_data()\fR function allows an application or engine to +replace the cipher data with new data. A pointer to any existing cipher data is +returned from this function. If the old data is no longer required then it +should be freed through a call to \fBOPENSSL_free()\fR. +.SH "RETURN VALUES" +.IX Header "RETURN VALUES" +The \fBEVP_CIPHER_CTX_get_cipher_data()\fR function returns a pointer to the current +cipher data for the EVP_CIPHER_CTX. +.PP +The \fBEVP_CIPHER_CTX_set_cipher_data()\fR function returns a pointer to the old +cipher data for the EVP_CIPHER_CTX. +.SH HISTORY +.IX Header "HISTORY" +The \fBEVP_CIPHER_CTX_get_cipher_data()\fR and \fBEVP_CIPHER_CTX_set_cipher_data()\fR +functions were added in OpenSSL 1.1.0. +.SH COPYRIGHT +.IX Header "COPYRIGHT" +Copyright 2016 The OpenSSL Project Authors.
