63 | .Sh DESCRIPTION | ||
64 | .Fn d2i_RSAPublicKey | ||
65 | and | ||
66 | .Fn i2d_RSAPublicKey | ||
67 | decode and encode a PKCS#1 RSAPublicKey structure. | ||
68 | .Pp | ||
69 | .Fn d2i_RSA_PUBKEY | ||
70 | and | ||
71 | .Fn i2d_RSA_PUBKEY | ||
72 | decode and encode an RSA public key using a SubjectPublicKeyInfo | ||
73 | (certificate public key) structure. | ||
74 | .Pp | ||
75 | .Fn d2i_RSAPrivateKey , | ||
76 | .Fn i2d_RSAPrivateKey | ||
77 | decode and encode a PKCS#1 RSAPrivateKey structure. | ||
78 | .Pp | ||
79 | .Fn d2i_Netscape_RSA , | ||
80 | .Fn i2d_Netscape_RSA | ||
81 | decode and encode an RSA private key in NET format. | ||
82 | .Pp | ||
83 | The usage of all of these functions is similar to | ||
84 | .Xr d2i_X509 3 | ||
85 | and | ||
86 | .Xr i2d_X509 3 . | ||
87 | .Pp | ||
88 | The | ||
89 | .Vt RSA | ||
90 | structure passed to the private key encoding functions should have all | ||
91 | the PKCS#1 private key components present. | ||
92 | .Pp | ||
93 | The data encoded by the private key functions is unencrypted and | ||
94 | therefore offers no private key security. | ||
95 | .Pp | ||
96 | The NET format functions are present to provide compatibility with | ||
97 | certain very old software. | ||
98 | This format has some severe security weaknesses and should be avoided if | ||
99 | possible. | ||
