[−]Struct openssl::ssl::SslOptions
Options controlling the behavior of an SslContext
.
Methods
impl SslOptions
pub const DONT_INSERT_EMPTY_FRAGMENTS: SslOptions
Disables a countermeasure against an SSLv3/TLSv1.0 vulnerability affecting CBC ciphers.
pub const ALL: SslOptions
A "reasonable default" set of options which enables compatibility flags.
pub const NO_QUERY_MTU: SslOptions
Do not query the MTU.
Only affects DTLS connections.
pub const COOKIE_EXCHANGE: SslOptions
Enables Cookie Exchange as described in RFC 4347 Section 4.2.1.
Only affects DTLS connections.
pub const NO_TICKET: SslOptions
Disables the use of session tickets for session resumption.
pub const NO_SESSION_RESUMPTION_ON_RENEGOTIATION: SslOptions
Always start a new session when performing a renegotiation on the server side.
pub const NO_COMPRESSION: SslOptions
Disables the use of TLS compression.
pub const ALLOW_UNSAFE_LEGACY_RENEGOTIATION: SslOptions
Allow legacy insecure renegotiation with servers or clients that do not support secure renegotiation.
pub const SINGLE_ECDH_USE: SslOptions
Creates a new key for each session when using ECDHE.
This is always enabled in OpenSSL 1.1.0.
pub const SINGLE_DH_USE: SslOptions
Creates a new key for each session when using DHE.
This is always enabled in OpenSSL 1.1.0.
pub const CIPHER_SERVER_PREFERENCE: SslOptions
Use the server's preferences rather than the client's when selecting a cipher.
This has no effect on the client side.
pub const TLS_ROLLBACK_BUG: SslOptions
Disables version rollback attach detection.
pub const NO_SSLV2: SslOptions
Disables the use of SSLv2.
pub const NO_SSLV3: SslOptions
Disables the use of SSLv3.
pub const NO_TLSV1: SslOptions
Disables the use of TLSv1.0.
pub const NO_TLSV1_1: SslOptions
Disables the use of TLSv1.1.
pub const NO_TLSV1_2: SslOptions
Disables the use of TLSv1.2.
pub const NO_DTLSV1: SslOptions
Disables the use of DTLSv1.0
Requires OpenSSL 1.0.2 or newer.
pub const NO_DTLSV1_2: SslOptions
Disables the use of DTLSv1.2.
Requires OpenSSL 1.0.2, or newer.
pub const NO_SSL_MASK: SslOptions
Disables the use of all (D)TLS protocol versions.
This can be used as a mask when whitelisting protocol versions.
Requires OpenSSL 1.0.2 or newer.
Examples
Only support TLSv1.2:
use openssl::ssl::SslOptions; let options = SslOptions::NO_SSL_MASK & !SslOptions::NO_TLSV1_2;
pub const fn empty() -> SslOptions
Returns an empty set of flags
pub const fn all() -> SslOptions
Returns the set containing all flags.
pub const fn bits(&self) -> c_ulong
Returns the raw value of the flags currently stored.
pub fn from_bits(bits: c_ulong) -> Option<SslOptions>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
pub const fn from_bits_truncate(bits: c_ulong) -> SslOptions
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
pub const unsafe fn from_bits_unchecked(bits: c_ulong) -> SslOptions
Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).
pub const fn is_empty(&self) -> bool
Returns true
if no flags are currently stored.
pub const fn is_all(&self) -> bool
Returns true
if all flags are currently set.
pub const fn intersects(&self, other: SslOptions) -> bool
Returns true
if there are flags common to both self
and other
.
pub const fn contains(&self, other: SslOptions) -> bool
Returns true
all of the flags in other
are contained within self
.
pub fn insert(&mut self, other: SslOptions)
Inserts the specified flags in-place.
pub fn remove(&mut self, other: SslOptions)
Removes the specified flags in-place.
pub fn toggle(&mut self, other: SslOptions)
Toggles the specified flags in-place.
pub fn set(&mut self, other: SslOptions, value: bool)
Inserts or removes the specified flags depending on the passed value.
