|
|
.Sh DESCRIPTION
|
|
These functions are used to encrypt and decrypt data.
|
|
.Pp
|
|
.Fn krb5_encrypt
|
|
puts the encrypted version of
|
|
.Fa data
|
|
(of size
|
|
.Fa len )
|
|
in
|
|
.Fa result .
|
|
If the encryption type supports using derived keys,
|
|
.Fa usage
|
|
should be the appropriate key-usage.
|
|
.Fn krb5_encrypt_EncryptedData
|
|
does the same as
|
|
.Fn krb5_encrypt ,
|
|
but it puts the encrypted data in a
|
|
.Fa EncryptedData
|
|
structure instead. If
|
|
.Fa kvno
|
|
is not zero, it will be put in the
|
|
.Fa kvno field in the
|
|
.Fa EncryptedData .
|
|
.Pp
|
|
.Fn krb5_decrypt ,
|
|
and
|
|
.Fn krb5_decrypt_EncryptedData
|
|
works similarly.
