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.
