SYNOPSIS

10        #include <openssl/evp.h>
11
12        const EVP_CIPHER *EVP_idea_cbc(void);
13        const EVP_CIPHER *EVP_idea_cfb(void);
14        const EVP_CIPHER *EVP_idea_cfb64(void);
15        const EVP_CIPHER *EVP_idea_ecb(void);
16        const EVP_CIPHER *EVP_idea_ofb(void);

DESCRIPTION

19       The IDEA encryption algorithm for EVP.
20
21       EVP_idea_cbc(), EVP_idea_cfb(), EVP_idea_cfb64(), EVP_idea_ecb(),
22       EVP_idea_ofb()
23           The IDEA encryption algorithm in CBC, CFB, ECB and OFB modes
24           respectively.
25

NOTES

27       Developers should be aware of the negative performance implications of
28       calling these functions multiple times and should consider using
29       EVP_CIPHER_fetch(3) instead.  See "Performance" in crypto(7) for
30       further information.
31

RETURN VALUES

33       These functions return an EVP_CIPHER structure that contains the
34       implementation of the symmetric cipher. See EVP_CIPHER_meth_new(3) for
35       details of the EVP_CIPHER structure.
