Member Function Documentation

Digest() [1/2]

byte [] iText.Commons.Digest.IMessageDigest.Digest

(

)

Completes the hash computation by performing final operations such as padding. Leaves the digest reset.

Returns

The array of bytes for the resulting hash value

Implemented in iText.Bouncycastlefips.Crypto.DigestBCFips, iText.Bouncycastle.Crypto.DigestBC, and iText.Commons.Bouncycastle.Crypto.IDigest.

Digest() [2/2]

byte [] iText.Commons.Digest.IMessageDigest.Digest

(

byte[]

enc

)

Performs a final update on the digest using the specified array of bytes, then completes the digest computation.

Parameters

enc	the input to be updated before the digest is completed

Returns

The array of bytes for the resulting hash value

Implemented in iText.Bouncycastlefips.Crypto.DigestBCFips, iText.Bouncycastle.Crypto.DigestBC, and iText.Commons.Bouncycastle.Crypto.IDigest.

GetAlgorithmName()

string iText.Commons.Digest.IMessageDigest.GetAlgorithmName

(

)

Returns a string that identifies the algorithm, independent of implementation details.

Returns

The name of the algorithm.

Implemented in iText.Bouncycastlefips.Crypto.DigestBCFips, iText.Bouncycastle.Crypto.DigestBC, and iText.Commons.Bouncycastle.Crypto.IDigest.

GetDigestLength()

int iText.Commons.Digest.IMessageDigest.GetDigestLength

(

)

Gets byte length of wrapped digest algorithm.

Returns

The length of the digest in bytes.

Implemented in iText.Bouncycastlefips.Crypto.DigestBCFips, iText.Bouncycastle.Crypto.DigestBC, and iText.Commons.Bouncycastle.Crypto.IDigest.

Reset()

void iText.Commons.Digest.IMessageDigest.Reset

(

)

Resets the digest for further use.

Implemented in iText.Bouncycastlefips.Crypto.DigestBCFips, iText.Bouncycastle.Crypto.DigestBC, and iText.Commons.Bouncycastle.Crypto.IDigest.

Update() [1/2]

void iText.Commons.Digest.IMessageDigest.Update

(

byte[]

buf

)

Updates the digest using the specified array of bytes.

Parameters

buf	byte array buffer

Implemented in iText.Bouncycastlefips.Crypto.DigestBCFips, iText.Bouncycastle.Crypto.DigestBC, and iText.Commons.Bouncycastle.Crypto.IDigest.

Update() [2/2]

void iText.Commons.Digest.IMessageDigest.Update	(	byte[]	buf,
		int	off,
		int	len
	)

Updates the digest using the specified array of bytes, starting at the specified offset.

Parameters

buf	byte array buffer
off	the offset to start from in the array of bytes
len	the number of bytes to use, starting at offset

Implemented in iText.Bouncycastlefips.Crypto.DigestBCFips, iText.Bouncycastle.Crypto.DigestBC, and iText.Commons.Bouncycastle.Crypto.IDigest.
