EVP_idea_cbc(3)                     OpenSSL                    EVP_idea_cbc(3)



NAME
       EVP_idea_cbc, EVP_idea_cfb, EVP_idea_cfb64, EVP_idea_ecb, EVP_idea_ofb
       - EVP IDEA cipher

LIBRARY
       libcrypto, -lcrypto

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.
