NAME

       EVP_cast5_cbc, EVP_cast5_cfb, EVP_cast5_cfb64, EVP_cast5_ecb, EVP_cast5_ofb - EVP CAST cipher

SYNOPSIS

        #include <openssl/evp.h>

        const EVP_CIPHER *EVP_cast5_cbc(void);
        const EVP_CIPHER *EVP_cast5_cfb(void);
        const EVP_CIPHER *EVP_cast5_cfb64(void);
        const EVP_CIPHER *EVP_cast5_ecb(void);
        const EVP_CIPHER *EVP_cast5_ofb(void);

DESCRIPTION

       The CAST encryption algorithm for EVP.

       This is a variable key length cipher.

       EVP_cast5_cbc(), EVP_cast5_ecb(), EVP_cast5_cfb(), EVP_cast5_cfb64(), EVP_cast5_ofb()
           CAST encryption algorithm in CBC, ECB, CFB 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-CAST(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.
