Other than the use of DER as opposed to PEM these functions are identi- cal to the corresponding PPEEMM function as described in the _p_e_m(3) manual page. NNOOTTEESS Before using these functions _O_p_e_n_S_S_L___a_d_d___a_l_l___a_l_g_o_r_i_t_h_m_s(3) should be called to initialize the internal algorithm lookup tables otherwise errors about unknown algorithms will occur if an attempt is made to decrypt a private key. These functions are currently the only way to store encrypted private keys using DER format. Currently all the functions use BIOs or FILE pointers, there are no functions which work directly on memory: this can be readily worked around by converting the buffers to memory BIOs, see _B_I_O___s___m_e_m(3) for details.
