-.TH IPSEC_ATOSA 3 "11 June 2001"
-.SH NAME
-ipsec atosa, satoa \- convert IPsec Security Association IDs to and from ASCII
-.SH SYNOPSIS
-.B "#include <freeswan.h>
-.sp
-.B "const char *atosa(const char *src, size_t srclen,"
-.ti +1c
-.B "struct sa_id *sa);
-.br
-.B "size_t satoa(struct sa_id sa, int format,"
-.ti +1c
-.B "char *dst, size_t dstlen);"
-.sp
-.B "struct sa_id {"
-.ti +1c
-.B "struct in_addr dst;"
-.ti +1c
-.B "ipsec_spi_t spi;"
-.ti +1c
-.B "int proto;"
-.br
-.B "};"
-.SH DESCRIPTION
-These functions are obsolete; see
-.IR ipsec_ttosa (3)
-for their replacements.
-.PP
-.I Atosa
-converts an ASCII Security Association (SA) specifier into an
-.B sa_id
-structure (containing
-a destination-host address
-in network byte order,
-an SPI number in network byte order, and
-a protocol code).
-.I Satoa
-does the reverse conversion, back to an ASCII SA specifier.
-.PP
-An SA is specified in ASCII with a mail-like syntax, e.g.
-.BR esp507@1.2.3.4 .
-An SA specifier contains
-a protocol prefix (currently
-.BR ah ,
-.BR esp ,
-or
-.BR tun ),
-an unsigned integer SPI number,
-and an IP address.
-The SPI number can be decimal or hexadecimal
-(with
-.B 0x
-prefix), as accepted by
-.IR ipsec_atoul (3).
-The IP address can be any form accepted by
-.IR ipsec_atoaddr (3),
-e.g. dotted-decimal address or DNS name.
-.PP
-As a special case, the SA specifier
-.B %passthrough
-signifies the special SA used to indicate that packets should be
-passed through unaltered.
-(At present, this is a synonym for
-.BR tun0x0@0.0.0.0 ,
-but that is subject to change without notice.)
-This form is known to both
-.I atosa
-and
-.IR satoa ,
-so the internal form of
-.B %passthrough
-is never visible.
-.PP
-The
-.B <freeswan.h>
-header file supplies the
-.B sa_id
-structure, as well as a data type
-.B ipsec_spi_t
-which is an unsigned 32-bit integer.
-(There is no consistency between kernel and user on what such a type
-is called, hence the header hides the differences.)
-.PP
-The protocol code uses the same numbers that IP does.
-For user convenience, given the difficulty in acquiring the exact set of
-protocol names used by the kernel,
-.B <freeswan.h>
-defines the names
-.BR SA_ESP ,
-.BR SA_AH ,
-and
-.B SA_IPIP
-to have the same values as the kernel names
-.BR IPPROTO_ESP ,
-.BR IPPROTO_AH ,
-and
-.BR IPPROTO_IPIP .
-.PP
-The
-.I srclen
-parameter of
-.I atosa
-specifies the length of the ASCII string pointed to by
-.IR src ;
-it is an error for there to be anything else
-(e.g., a terminating NUL) within that length.
-As a convenience for cases where an entire NUL-terminated string is
-to be converted,
-a
-.I srclen
-value of
-.B 0
-is taken to mean
-.BR strlen(src) .
-.PP
-The
-.I dstlen
-parameter of
-.I satoa
-specifies the size of the
-.I dst
-parameter;
-under no circumstances are more than
-.I dstlen
-bytes written to
-.IR dst .
-A result which will not fit is truncated.
-.I Dstlen
-can be zero, in which case
-.I dst
-need not be valid and no result is written,
-but the return value is unaffected;
-in all other cases, the (possibly truncated) result is NUL-terminated.
-The
-.I freeswan.h
-header file defines a constant,
-.BR SATOA_BUF ,
-which is the size of a buffer just large enough for worst-case results.
-.PP
-The
-.I format
-parameter of
-.I satoa
-specifies what format is to be used for the conversion.
-The value
-.B 0
-(not the ASCII character
-.BR '0' ,
-but a zero value)
-specifies a reasonable default
-(currently
-lowercase protocol prefix, lowercase hexadecimal SPI, dotted-decimal address).
-The value
-.B d
-causes the SPI to be generated in decimal instead.
-.PP
-.I Atosa
-returns
-.B NULL
-for success and
-a pointer to a string-literal error message for failure;
-see DIAGNOSTICS.
-.I Satoa
-returns
-.B 0
-for a failure, and otherwise
-always returns the size of buffer which would 
-be needed to
-accommodate the full conversion result, including terminating NUL;
-it is the caller's responsibility to check this against the size of
-the provided buffer to determine whether truncation has occurred.
-.SH SEE ALSO
-ipsec_atoul(3), ipsec_atoaddr(3), inet(3)
-.SH DIAGNOSTICS
-Fatal errors in
-.I atosa
-are:
-empty input;
-input too small to be a legal SA specifier;
-no
-.B @
-in input;
-unknown protocol prefix;
-conversion error in
-.I atoul
-or
-.IR atoaddr .
-.PP
-Fatal errors in

-The

-.PP
-The restriction of ASCII-to-binary error reports to literal strings
-(so that callers don't need to worry about freeing them or copying them)
-does limit the precision of error reporting.
-.PP
-The ASCII-to-binary error-reporting convention lends itself
-to slightly obscure code,
-because many readers will not think of NULL as signifying success.
-A good way to make it clearer is to write something like:
-.PP
-.RS

-.B "error = atoaddr( /* ... */ );"
-.B "if (error != NULL) {"

-.TH IPSEC_KEYBLOBTOID 3 "25 March 2002"
-.SH NAME
-ipsec keyblobtoid, splitkeytoid \- generate key IDs from RSA keys
-.SH SYNOPSIS
-.B "#include <freeswan.h>
-.sp
-.B "size_t keyblobtoid(const unsigned char *blob,"
-.ti +1c
-.B "size_t bloblen, char *dst, size_t dstlen);"
-.br
-.B "size_t splitkeytoid(const unsigned char *e, size_t elen,"
-.ti +1c
-.B "const unsigned char *m, size_t mlen, char *dst,
-.ti +1c
-.B "size_t dstlen);"
-.SH DESCRIPTION
-.I Keyblobtoid
-and
-.I splitkeytoid
-generate
-key IDs
-from RSA keys,
-for use in messages and reporting,
-writing the result to
-.IR dst .
-A
-.I key ID
-is a short ASCII string identifying a key;
-currently it is just the first nine characters of the base64
-encoding of the RFC 2537/3110 ``byte blob'' representation of the key.
-(Beware that no finite key ID can be collision-proof:
-there is always some small chance of two random keys having the
-same ID.)
-.PP
-.I Keyblobtoid
-generates a key ID from a key which is already in the form of an
-RFC 2537/3110 binary key
-.I blob
-(encoded exponent length, exponent, modulus).
-.PP
-.I Splitkeytoid
-generates a key ID from a key given in the form of a separate
-(binary) exponent
-.I e
-and modulus
-.IR m .
-.PP
-The
-.I dstlen
-parameter of either
-specifies the size of the
-.I dst
-parameter;
-under no circumstances are more than
-.I dstlen
-bytes written to
-.IR dst .
-A result which will not fit is truncated.
-.I Dstlen
-can be zero, in which case
-.I dst
-need not be valid and no result is written,
-but the return value is unaffected;
-in all other cases, the (possibly truncated) result is NUL-terminated.
-The
-.I freeswan.h
-header file defines a constant
-.B KEYID_BUF
-which is the size of a buffer large enough for worst-case results.
-.PP
-Both functions return
-.B 0
-for a failure, and otherwise
-always return the size of buffer which would 
-be needed to
-accommodate the full conversion result, including terminating NUL;
-it is the caller's responsibility to check this against the size of
-the provided buffer to determine whether truncation has occurred.
-.P
-With keys generated by
-.IR ipsec_rsasigkey (3),
-the first two base64 digits are always the same,
-and the third carries only about one bit of information.
-It's worse with keys using longer fixed exponents,
-e.g. the 24-bit exponent that's common in X.509 certificates.
-However, being able to relate key IDs to the full
-base64 text form of keys by eye is sufficiently useful that this
-waste of space seems justifiable.
-The choice of nine digits is a compromise between bulk and
-probability of collision.
-.SH SEE ALSO
-RFC 3110,
-\fIRSA/SHA-1 SIGs and RSA KEYs in the Domain Name System (DNS)\fR,
-Eastlake, 2001
-(superseding the older but better-known RFC 2537).
-.SH DIAGNOSTICS
-Fatal errors are:
-key too short to supply enough bits to construct a complete key ID
-(almost certainly indicating a garbage key);
-exponent too long for its length to be representable.
-.SH HISTORY
-Written for the FreeS/WAN project by Henry Spencer.

-initializes a crypto-quality pseudo-random-number generator from a key;
-.I prng_bytes
-obtains pseudo-random bytes from it;
-.I prng_count
-reports the number of bytes extracted from it to date;
-.I prng_final
-closes it down.
-It is the user's responsibility to initialize a PRNG before using it,
-and not to use it again after it is closed down.
-.PP
-.I Prng_init
-initializes,
-or re-initializes,
-the specified
-.I prng
-from the
-.IR key ,
-whose length is given by
-.IR keylen .
-The user must allocate the
-.B "struct prng"
-pointed to by
-.IR prng .
-There is no particular constraint on the length of the key,
-although a key longer than 256 bytes is unnecessary because
-only the first 256 would be used.
-Initialization requires on the order of 3000 integer operations,
-independent of key length.
-.PP
-.I Prng_bytes
-obtains
-.I dstlen
-pseudo-random bytes from the PRNG and puts them in
-.IR buf .
-This is quite fast,
-on the order of 10 integer operations per byte.
-.PP
-.I Prng_count
-reports the number of bytes obtained from the PRNG
-since it was (last) initialized.
-.PP
-.I Prng_final
-closes down a PRNG by
-zeroing its internal memory,
-obliterating all trace of the state used to generate its previous output.
-This requires on the order of 250 integer operations.
-.PP
-The
-.B <freeswan.h>
-header file supplies the definition of the
-.B prng
-structure.
-Examination of its innards is discouraged, as they may change.
-.PP
-The PRNG algorithm
-used by these functions is currently identical to that of RC4(TM).
-This algorithm is cryptographically strong,
-sufficiently unpredictable that even a hostile observer will
-have difficulty determining the next byte of output from past history,
-provided it is initialized from a reasonably large key composed of
-highly random bytes (see
-.IR random (4)).
-The usual run of software pseudo-random-number generators
-(e.g.
-.IR random (3))
-are
-.I not
-cryptographically strong.
-.PP
-The well-known attacks against RC4(TM),
-e.g. as found in 802.11b's WEP encryption system,
-apply only if multiple PRNGs are initialized with closely-related keys
-(e.g., using a counter appended to a base key).
-If such keys are used, the first few hundred pseudo-random bytes
-from each PRNG should be discarded,
-to give the PRNGs a chance to randomize their innards properly.
-No useful attacks are known if the key is well randomized to begin with.

-.SH HISTORY
-Written for the FreeS/WAN project by Henry Spencer.
-.SH BUGS
-If an attempt is made to obtain more than 4e9 bytes
-between initializations,
-the PRNG will continue to work but
-.IR prng_count 's
-output will stick at
-.BR 4000000000 .
-Fixing this would require a longer integer type and does
-not seem worth the trouble,
-since you should probably re-initialize before then anyway...
