| 32 | =head1 DESCRIPTION
|
|---|
| 33 |
|
|---|
| 34 | PKCS12_item_decrypt_d2i() and PKCS12_item_decrypt_d2i_ex() decrypt an octet
|
|---|
| 35 | string containing an ASN.1 encoded object using the algorithm I<algor> and
|
|---|
| 36 | password I<pass> of length I<passlen>. If I<zbuf> is nonzero then the output
|
|---|
| 37 | buffer will zeroed after the decrypt.
|
|---|
| 38 |
|
|---|
| 39 | PKCS12_item_i2d_encrypt() and PKCS12_item_i2d_encrypt_ex() encrypt an ASN.1
|
|---|
| 40 | object I<it> using the algorithm I<algor> and password I<pass> of length
|
|---|
| 41 | I<passlen>, returning an encoded object in I<obj>. If I<zbuf> is nonzero then
|
|---|
| 42 | the buffer containing the input encoding will be zeroed after the encrypt.
|
|---|
| 43 |
|
|---|
| 44 | Functions ending in _ex() allow for a library context I<ctx> and property query
|
|---|
| 45 | I<propq> to be used to select algorithm implementations.
|

| 46 |
|
|---|
| 47 | =head1 RETURN VALUES
|
|---|
| 48 |
|
|---|
| 49 | PKCS12_item_decrypt_d2i() and PKCS12_item_decrypt_d2i_ex() return the decrypted
|
|---|
| 50 | object or NULL if an error occurred.
|
|---|
| 51 |
|
|---|
| 52 | PKCS12_item_i2d_encrypt() and PKCS12_item_i2d_encrypt_ex() return the encrypted
|
|---|
| 53 | data as an ASN.1 Octet String or NULL if an error occurred.
