  71. The following functions have been deprecated since OpenSSL 3.0, and can be

  80. .SH DESCRIPTION
  81. .IX Header "DESCRIPTION"
  82. \&\fBRSA_new()\fR allocates and initializes an \fBRSA\fR structure. It is equivalent to
  83. calling RSA_new_method(NULL).
  84. .PP
  85. \&\fBRSA_free()\fR frees the \fBRSA\fR structure and its components. The key is
  86. erased before the memory is returned to the system.
  87. If \fBrsa\fR is NULL nothing is done.
  88. .SH "RETURN VALUES"
  89. .IX Header "RETURN VALUES"
  90. If the allocation fails, \fBRSA_new()\fR returns \fBNULL\fR and sets an error
  91. code that can be obtained by \fBERR_get_error\fR\|(3). Otherwise it returns
  92. a pointer to the newly allocated structure.
  93. .PP
  94. \&\fBRSA_free()\fR returns no value.
