"DESCRIPTION"
Header "DESCRIPTION" The \s-1RC2\s0 encryption algorithm for \s-1EVP.\s0
"EVP_rc2_cbc(), EVP_rc2_cfb(), EVP_rc2_cfb64(), EVP_rc2_ecb(), EVP_rc2_ofb()" 4
Item "EVP_rc2_cbc(), EVP_rc2_cfb(), EVP_rc2_cfb64(), EVP_rc2_ecb(), EVP_rc2_ofb()" \s-1RC2\s0 encryption algorithm in \s-1CBC, CFB, ECB\s0 and \s-1OFB\s0 modes respectively. This is a
variable key length cipher with an additional parameter called \*(L"effective key
bits\*(R" or \*(L"effective key length\*(R". By default both are set to 128 bits.
"EVP_rc2_40_cbc(), EVP_rc2_64_cbc()" 4
Item "EVP_rc2_40_cbc(), EVP_rc2_64_cbc()" \s-1RC2\s0 algorithm in \s-1CBC\s0 mode with a default key length and effective key length of
40 and 64 bits.
.Sp
\s-1WARNING:\s0 these functions are obsolete. Their usage should be replaced with the
\fBEVP_rc2_cbc(), EVP_CIPHER_CTX_set_key_length() and EVP_CIPHER_CTX_ctrl()
functions to set the key length and effective key length.
"NOTES"
Header "NOTES" Developers should be aware of the negative performance implications of
calling these functions multiple times and should consider using
\fBEVP_CIPHER_fetch\|(3) instead.
See \*(L"Performance\*(R" in crypto\|(7) for further information.
"RETURN VALUES"
Header "RETURN VALUES" These functions return an \s-1EVP_CIPHER\s0 structure that contains the
implementation of the symmetric cipher. See EVP_CIPHER_meth_new\|(3) for
details of the \s-1EVP_CIPHER\s0 structure.
