Function Documentation

ComputeMD5() [1/2]

bool Aws::Crt::Crypto::ComputeMD5 ( Allocator * allocator, const ByteCursor & input, ByteBuf & output, size_t truncateTo = 0 )

noexcept

Computes a MD5 Hash over input, and writes the digest to output. If truncateTo is non-zero, the digest will be truncated to the value of truncateTo. Returns true on success. If this function fails, Aws::Crt::LastError() will contain the error that occurred. Unless you're using 'truncateTo', output should have a minimum capacity of MD5_DIGEST_SIZE.

ComputeMD5() [2/2]

bool Aws::Crt::Crypto::ComputeMD5 ( const ByteCursor & input, ByteBuf & output, size_t truncateTo = 0 )

noexcept

Computes a MD5 Hash using the default allocator over input, and writes the digest to output. If truncateTo is non-zero, the digest will be truncated to the value of truncateTo. Returns true on success. If this function fails, Aws::Crt::LastError() will contain the error that occurred. Unless you're using 'truncateTo', output should have a minimum capacity of MD5_DIGEST_SIZE.

ComputeSHA1() [1/2]

bool Aws::Crt::Crypto::ComputeSHA1 ( Allocator * allocator, const ByteCursor & input, ByteBuf & output, size_t truncateTo = 0 )

noexcept

Computes a SHA1 Hash over input, and writes the digest to output. If truncateTo is non-zero, the digest will be truncated to the value of truncateTo. Returns true on success. If this function fails, Aws::Crt::LastError() will contain the error that occurred. Unless you're using 'truncateTo', output should have a minimum capacity of SHA1_DIGEST_SIZE.

ComputeSHA1() [2/2]

bool Aws::Crt::Crypto::ComputeSHA1 ( const ByteCursor & input, ByteBuf & output, size_t truncateTo = 0 )

noexcept

Computes a SHA1 Hash using the default allocator over input, and writes the digest to output. If truncateTo is non-zero, the digest will be truncated to the value of truncateTo. Returns true on success. If this function fails, Aws::Crt::LastError() will contain the error that occurred. Unless you're using 'truncateTo', output should have a minimum capacity of SHA1_DIGEST_SIZE.

ComputeSHA256() [1/2]

bool Aws::Crt::Crypto::ComputeSHA256 ( Allocator * allocator, const ByteCursor & input, ByteBuf & output, size_t truncateTo = 0 )

noexcept

Computes a SHA256 Hash over input, and writes the digest to output. If truncateTo is non-zero, the digest will be truncated to the value of truncateTo. Returns true on success. If this function fails, Aws::Crt::LastError() will contain the error that occurred. Unless you're using 'truncateTo', output should have a minimum capacity of SHA256_DIGEST_SIZE.

ComputeSHA256() [2/2]

bool Aws::Crt::Crypto::ComputeSHA256 ( const ByteCursor & input, ByteBuf & output, size_t truncateTo = 0 )

noexcept

Computes a SHA256 Hash using the default allocator over input, and writes the digest to output. If truncateTo is non-zero, the digest will be truncated to the value of truncateTo. Returns true on success. If this function fails, Aws::Crt::LastError() will contain the error that occurred. Unless you're using 'truncateTo', output should have a minimum capacity of SHA256_DIGEST_SIZE.

ComputeSHA256HMAC() [1/2]

bool Aws::Crt::Crypto::ComputeSHA256HMAC ( Allocator * allocator, const ByteCursor & secret, const ByteCursor & input, ByteBuf & output, size_t truncateTo = 0 )

noexcept

Computes a SHA256 HMAC with secret over input, and writes the digest to output. If truncateTo is non-zero, the digest will be truncated to the value of truncateTo. Returns true on success. If this function fails, Aws::Crt::LastError() will contain the error that occurred. Unless you're using 'truncateTo', output should have a minimum capacity of SHA256_HMAC_DIGEST_SIZE.

ComputeSHA256HMAC() [2/2]

bool Aws::Crt::Crypto::ComputeSHA256HMAC ( const ByteCursor & secret, const ByteCursor & input, ByteBuf & output, size_t truncateTo = 0 )

noexcept

Computes a SHA256 HMAC using the default allocator with secret over input, and writes the digest to output. If truncateTo is non-zero, the digest will be truncated to the value of truncateTo. Returns true on success. If this function fails, Aws::Crt::LastError() will contain the error that occurred. Unless you're using 'truncateTo', output should have a minimum capacity of SHA256_HMAC_DIGEST_SIZE.

ComputeSHA512() [1/2]

bool Aws::Crt::Crypto::ComputeSHA512 ( Allocator * allocator, const ByteCursor & input, ByteBuf & output, size_t truncateTo = 0 )

noexcept

Computes a SHA512 Hash over input, and writes the digest to output. If truncateTo is non-zero, the digest will be truncated to the value of truncateTo. Returns true on success. If this function fails, Aws::Crt::LastError() will contain the error that occurred. Unless you're using 'truncateTo', output should have a minimum capacity of SHA512_DIGEST_SIZE.

ComputeSHA512() [2/2]

bool Aws::Crt::Crypto::ComputeSHA512 ( const ByteCursor & input, ByteBuf & output, size_t truncateTo = 0 )

noexcept

Computes a SHA512 Hash using the default allocator over input, and writes the digest to output. If truncateTo is non-zero, the digest will be truncated to the value of truncateTo. Returns true on success. If this function fails, Aws::Crt::LastError() will contain the error that occurred. Unless you're using 'truncateTo', output should have a minimum capacity of SHA512_DIGEST_SIZE.

DeriveSHA512HMACHKDF()

bool Aws::Crt::Crypto::DeriveSHA512HMACHKDF ( Allocator * allocator, ByteCursor ikm, ByteCursor salt, ByteCursor info, ByteBuf & out, size_t length )

noexcept

Derives an SHA256 HMAC HKDF using the default allocator and writes it to out. If this function fails, Aws::Crt::LastError() will contain the error that occurred.
