SHA-1 input data was malformed.

struct mbedtls_sha1_context typedef struct mbedtls_sha1_context mbedtls_sha1_context mbedtls_sha1_context

The SHA-1 context structure.

SHA-1 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

void void mbedtls_sha1_init (mbedtls_sha1_context *ctx) mbedtls_sha1_init mbedtls_sha1_context * ctx

This function initializes a SHA-1 context.

SHA-1 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

ctx

The SHA-1 context to initialize. This must not be `NULL`.

void void mbedtls_sha1_free (mbedtls_sha1_context *ctx) mbedtls_sha1_free mbedtls_sha1_context * ctx

This function clears a SHA-1 context.

SHA-1 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

ctx

The SHA-1 context to clear. This may be `NULL`, in which case this function does nothing. If it is not `NULL`, it must point to an initialized SHA-1 context.

void void mbedtls_sha1_clone (mbedtls_sha1_context *dst, const mbedtls_sha1_context *src) mbedtls_sha1_clone mbedtls_sha1_context * dst const mbedtls_sha1_context * src

This function clones the state of a SHA-1 context.

SHA-1 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

dst

The SHA-1 context to clone to. This must be initialized.

src

The SHA-1 context to clone from. This must be initialized.

int int mbedtls_sha1_starts (mbedtls_sha1_context *ctx) mbedtls_sha1_starts mbedtls_sha1_context * ctx

This function starts a SHA-1 checksum calculation.

SHA-1 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

ctx

The SHA-1 context to initialize. This must be initialized.

`0` on success.

A negative error code on failure.

int int mbedtls_sha1_update (mbedtls_sha1_context *ctx, const unsigned char *input, size_t ilen) mbedtls_sha1_update mbedtls_sha1_context * ctx const unsigned char * input size_t ilen

This function feeds an input buffer into an ongoing SHA-1 checksum calculation.

SHA-1 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

ctx

The SHA-1 context. This must be initialized and have a hash operation started.

input

The buffer holding the input data. This must be a readable buffer of length `ilen` Bytes.

ilen

The length of the input data `input` in Bytes.

`0` on success.

A negative error code on failure.

int int mbedtls_sha1_finish (mbedtls_sha1_context *ctx, unsigned char output[20]) mbedtls_sha1_finish mbedtls_sha1_context * ctx unsigned char output [20]

This function finishes the SHA-1 operation, and writes the result to the output buffer.

SHA-1 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

ctx

The SHA-1 context to use. This must be initialized and have a hash operation started.

output

The SHA-1 checksum result. This must be a writable buffer of length `20` Bytes.

`0` on success.

A negative error code on failure.

int int mbedtls_internal_sha1_process (mbedtls_sha1_context *ctx, const unsigned char data[64]) mbedtls_internal_sha1_process mbedtls_sha1_context * ctx const unsigned char data [64]

SHA-1 process data block (internal use only).

SHA-1 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

ctx

The SHA-1 context to use. This must be initialized.

data

The data block being processed. This must be a readable buffer of length `64` Bytes.

`0` on success.

A negative error code on failure.

int int mbedtls_sha1 (const unsigned char *input, size_t ilen, unsigned char output[20]) mbedtls_sha1 const unsigned char * input size_t ilen unsigned char output [20]

This function calculates the SHA-1 checksum of a buffer.

The function allocates the context, performs the calculation, and frees the context. The SHA-1 result is calculated as output = SHA-1(input buffer).

SHA-1 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

input

The buffer holding the input data. This must be a readable buffer of length `ilen` Bytes.

ilen

The length of the input data `input` in Bytes.

output

The SHA-1 checksum result. This must be a writable buffer of length `20` Bytes.

`0` on success.

A negative error code on failure.

int int mbedtls_sha1_self_test (int verbose) mbedtls_sha1_self_test int verbose

The SHA-1 checkup routine.

SHA-1 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

`0` on success.

`1` on failure.

This file contains SHA-1 definitions and functions.

The Secure Hash Algorithm 1 (SHA-1) cryptographic hash function is defined in FIPS 180-4: Secure Hash Standard (SHS).

SHA-1 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.
