EVP_IDEA_CBC(3SSL) OpenSSL EVP_IDEA_CBC(3SSL)
NAME
EVP_idea_cbc, EVP_idea_cfb, EVP_idea_cfb64, EVP_idea_ecb, EVP_idea_ofb -
EVP IDEA cipher
SYNOPSIS
#include <openssl/evp.h>
const EVP_CIPHER *EVP_idea_cbc(void);
const EVP_CIPHER *EVP_idea_cfb(void);
const EVP_CIPHER *EVP_idea_cfb64(void);
const EVP_CIPHER *EVP_idea_ecb(void);
const EVP_CIPHER *EVP_idea_ofb(void);
DESCRIPTION
The IDEA encryption algorithm for EVP.
EVP_idea_cbc(), EVP_idea_cfb(), EVP_idea_cfb64(), EVP_idea_ecb(),
EVP_idea_ofb()
The IDEA encryption algorithm in CBC, CFB, ECB and OFB modes
respectively.
NOTES
Developers should be aware of the negative performance implications of
calling these functions multiple times and should consider using
EVP_CIPHER_fetch(3) with EVP_CIPHER-IDEA(7) instead. See "Performance"
in crypto(7) for further information.
RETURN VALUES
These functions return an EVP_CIPHER structure that contains the
implementation of the symmetric cipher. See EVP_CIPHER_meth_new(3) for
details of the EVP_CIPHER structure.
